Question

The volume of a cube is 216 cubic units. What is the length of each edge? Explain how you know.

Answer 1

The length of each edge is 6 cubic units because 216/6= 36 and 6*6*6=36 and 36is the area of each face in the cube

Answer 2

Volume = s*s*s = s^3
A cube have equal sides, the length is s the width is s and the height is s.


216 = x^3

x = cuberoot of 216

x = 6 units
