A cube is painted with green colour on it's five faces .If this cube is cut into equal 125 small cubes . How many small cubes will have no face coloured.

27 faces have no face colored

Step-by-step explanation:

Divide the cube into 125 parts . This can be done by dividing the length,breadth and height of the cube in 5 equal parts each.

A cube painted green on all faces, is divided into 125 small cubes. l x bx h = 125

L= 5,   B = 5 , H = 5

A cube has 6 faces

Let A & B be 1st pair of opposite lateral faces

C & D be 2nd pair of opposite lateral faces

E be Top face

F be bottom face

Now we find out the total number of colored faces =

Face A contains = 25 cubes ( l x h = 5x5)

Face B contains= 25 cubes( l x h = 5x5)

Face C contains = 15 cubes( b x h = 3 x5)  

Face D contains =15 cubes( b xh= 3x5)

Face E contains= 9 cubes ( l x b= 3x3)

Face F contains = 9 cubes ( l x b= 3x3)

So total number of painted faces = 25+25+15+15+9+9= 98 cubes

The number of cubes not painted on any of the faces = 125 — 98 = 27

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
