The question
Question: find the volume of a cube with sides 10 m.
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 = 10.
V = 10 × 10 × 10
10 times 10 is 100.
That is one layer of 100 cubes.
So V = 100 × 10: 10 layers of 100.
V = 100 × 10
100 times 10 is 1000.
We count cubes, so the unit is m³.
So the volume is 1000 m³.
V = 1000 m3
Answer
V = 1000 m3
