The question

Question: find the volume of a cube with sides 5.

1 Side × side × side

Volume is how much space is inside.

We count the 1 by 1 by 1 cubes that fit.

All the sides of a cube are the same.

So the volume is V = side × side × side.

V = side × side × side

Now put the numbers in: side = 5.

V = 5 × 5 × 5

5 times 5 is 25.

That is one layer of 25 cubes.

So V = 25 × 5: 5 layers of 25.

V = 25 × 5

25 times 5 is 125.

So the volume is 125 cubic units.

V = 125
Answer
V = 125
