Question

The volume of a cube is 1000mm3. What is the length of its side?

Answer 1

a cube's volume is length * hight * width

since it is a cube, length hight width are all the same.

so we can use variable x to represent it.

x*x*x

which is

`{ x}^(3)`

so


`{x}^(3) = 1000`
cube root both sides


`x = \sqrt[3]{1000} = 10`

length of its side is 10
