Question

What equation can I use to find the side of a cube whose area is 729?

Answer 1

#1 There is no area of a cube. There is only a volume.
#2 The formula is
`V = s^(3)` where s is the side.

Substitute 729 in V since that is the volume.

`729 = s^(3)`

Take the cube root and you will get 9.

So the formula is
`V = s^(3)` and the side is 9.
