How many cubes with side lengths of 1/2 cm can fit inside the rectangular prism

7/2 or 3.5 inches

Step-by-step explanation:

The volume of the rectangle=

length×width×height, so

V=1/2×2×7/2

V=1×7/2

V=7/2 cubic inches

Next, Volume of the cube=

side^3, or side×side×side

V=1/2×1/2×1/2

V=1/8 cubic inches

First question,

To find how many cubes with the side of 1/2 length that fir into the rectangular prism, take:

7/2÷1/8

=7/2×8

=28 cubes. As a result, there are 28 cubes that will fit into the prism

Second question,

The volume of the person is 7/2 cubic inches or 3.5 cubic inches. Hope it help!

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
