Question

What is the length of a side of a cube with a volume of 216 in3

Answer 1

hi!

Answer 2

it will be the cubed root \[\sqrt[3]{216}=6\]

Answer 3

Each face of a cube is a square and we know that the sides of a square are all equal. Therefore, all the sides of a cube are also equal. The volume is given by
\[Vol = L \times W \times H\]
Since all the sides are the same,
\[L = W = H = x\]
In the above line, I set them equal to a variable 'x'
We know the volume is then given by
\[Vol = x^3 = 216 \ in^3\]
We can then solve for x by using what @misty1212 suggested, which is the cube root.
