The answer is 7.
1*10^-4 equals 0.001 and 7*10^-4 equals 0.007 so 0.007 divided by 0.001 is 7. I hope this makes sense !
As with hardwood and softwood sizes, plywood sizes can be somewhat confusing. Plywood sheets are usually sold as four-feet wide but are occasionally found in two and five-foot widths. Similarly, a plywood sheet's length is commonly eight feet, but some suppliers carry four and 12-foot lengths. Metric sizes are also available.Plywood Sizes
While the length and width of a sheet are pretty straightforward, the thickness dimensions are anything but.
The most common sizes of plywood sold in the United States are 3/4", 1/2", and 1/4". However, that's not exactly correct. A 3/4" sheet of plywood is really 23/32" (and is now typically labeled as such). Similarly, 1/2" should be correctly labeled as 15/32" and 1/4" labeled as 7/32". However, everyone still refers to them as 3/4", 1/2", and 1/4".
Although it doesn't seem like much, this 1/32" differential between the actual size and the common size can become an issue when working with plywood. For instance, if a woodworker is building a bookshelf where a 3/4" plywood shelf is placed into a dado cut into the shelf standards, there will be a very noticeable 1/32" gap, and the shelf will feel a bit sloppy in the dado. To combat this, the dado should be cut at 23/32" to ensure a proper fit.Other Wood Sizing
Are other types of wood affected by this interesting but inconsistent model of measurement?
Try finding a 2x4 that actually measures two inches by four inches. Instead, if you pull out a tape measure, you'll find that the 2x4 actually measures 1-1/2 inches by 3-1/2 inches in size. You'll find that a 2x6 is similarly one-half inch thinner and narrower than advertised. One-by material can be even more confusing because the one-half inch rule only applies to one side.
For instance, a 1x4 will actually measure 3/4-inch thick by 3-1/2 inches in size.
While this rule applies to dimensional lumber, particularly the SPF stock that is prevalent in home centers but often used for home building, it doesn't apply to hardwoods and exotics sold by fine woodworking suppliers. These woods are instead sold by the board-foot, so the actual measurements of the length, width and thickness are used to calculate the cost of each individual board. As such, when buying hardwoods, you may end with two boards that are the exact same size in terms of board-feet, but the boards are obviously very different along the length, width or thickness.Why Isn't a 3/4-Inch Sheet Actually 3/4-Inches Thick?
The question most commonly posed when people learn of the variations in wood sizes is, "why can't they just sell a two-inch thick by four-inch wide board when I buy a 2x4?"
There are two answers commonly given. The first is that manufacturers determined that if they shrunk the sizes of each piece slightly, they could get more pieces of sellable material out of each and every tree that they harvest. Over the economies of scale, 1/32-inch in each piece of plywood can add a considerable amount of extra income for the manufacturer.
A less cynical answer would be that the reduced sizes actually are adjusted for home building purposes. For instance, a six-inch thick wall can be completed easily using a 5-1/2 inch wide wall stud and a 1/2-inch thick sheet of drywall applied on the face of the framed wall.

inquiry or some options.
A rectangle has length and width. In this the two lengths and the two width would be equal.
Perimeter = length + breadth + length + breadth
Perimeter = 2 ( length + breadth )
Let's take the measure of the width as ' w '
Then, the length is given by 3 meters less than double the width
double the width = 2w
3 less than double the width = 2w - 3
Hence, the measure of the length is 2w - 3
Now, let's plug in these values for the perimeter :
2 ( w + 2w - 3 )
Given perimeter is 42 meters
2 ( w + 2w - 3 ) = 42
... 2 ( 3w - 3 ) = 42
... 6w - 6 = 42
Adding 6 on both sides
... 6w = 48
Dividing by 6 on both sides
... w = 48 / 6
... w = 8
Hence, the width is 8 meters
We know the width is 8 meters and the length is 2w - 3
Now plug in the values...
... 2 ( 8 ) - 3
... 16 - 3
... 13 meters.
Hence, the width is 8 meters and the length is 13 meters.
Hope my answer helps!!
Let L and b be the Length and breadth of Rectangular Piece of sheet metal
Square piece of 44 in. is cut from each corner
thus New length of cuboid is
Breadth of Cuboid
Height of breadth is
Volume of Cuboid
substitute the value of L i n volume
If the first cake and the second cake are the same size, they'd have the same area and the same volume.
Ratio between 1st pieces and 2nd pieces:
24:40 = 6:10
So for every 3 pieces from the first cake, you get 5 pieces from the second cake.
Therefore, your volume of each piece of the second cake should be 45 cm^3.
Since the height is given as 3 cm, the area of each piece of the second cake should be 15 cm^2. (45/3 = 15)
Working with whole numbers (i'm assuming), the possible dimensions of the second cake pieces would be: 5 cm x 3 cm x 3 cm (and since 3 and 5 are the only integer factors of 15).
Your width x length = 5 cm x 3 cm (or vice versa)
L = 2w - 3
perimeter = 24 meters
p = 24m
p = 2L + 2w
24 = 2(2w-3) + 2w ( Remember L = 2w +3)
24 = 4w -6 +2w
24 = 6w + 6
24 - 6 = 6w
18 = 6w
18/6 = w
3 = w
Now that we know ,w, we can find L.
p = 2L + 2w
24 = 2L +2(3)
24 = 2L + 6
24 -6 = 2L
18 = 2L
18/2 = L
9 = L
Now, we can check if the answer makes sense.
p = 2L + 2w
24 = 2(9) + 2(3) (L = 9 & w =3 )
24 = 18 + 6
24 = 24
the answer checks!
If the width of the original piece of sheet metal is x, then the length is 2x-10. Subtracting a 5" square from each corner makes the bottom of the box have dimensions (x-10) and (2x-20). The volume of the box is then ...
5(x -10)(2x -20) = 1210 . . . . . . volume is the product of the dimensions
10(x -10)² = 1210 = 10(11²) . . . . factor the equation
(x -10)² = 11² . . . . . . . . divide by 10
x = 11 + 10 = 21 . . . . . .take the square root, add 10
The length and width of the original piece of sheet metal were 32 inches and 21 inches, respectively.
3n-2 = length
perimeter = 68m
so 2(n+3n-2) =68 (n+3n-2) = one width and one length - just half way
around the rectangle - that's why I multiplied the entire expression by the 2 outside the parentheses.
Now simplify inside the parenthesis and you get
2 (4n-2) = 68
Now multiply and make sure you use the distributive law
8n - 4 = 68
Add 4 to both sides
8n = 72 now divide both sides by 8 and you get n=9
so the width is 9 and the length (3n-2) = 3x9-2 or 25
Check: 2(l+w) = 68 (perimeter) 2(9+25) = 68 2(34) = 68 68=68
So the width is 9 and the length is 25
i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
