Question

The volume of a cube is 27 cubic yards. Find the side length.

9 yards
6 yards
3 yards
None of the choices are correct.

Answer 1

Since all sides of a cube are equal...,

Let one side length of a cube be (z)

;Volume = z × z × z

;Volume = z^3

; 27 = z^3....where we then say that..,

; z(side length) = cube root of (27)

; Hence..., Side Length = 3 yards
