Question

Side length of 216 cubic yards

Answer 1

6 yards

Explanation:

The volume of a cube can be found using the following formula.

`v= s^3`

We know the volume is 216 cubic yards, so we can substitute 216 yd³ in for v.

`216 yd^3=s^3`

We want to find the side length. Therefore, we must isolate the variable, s, on one side of the equation.

s is being cubed. The inverse of cubed is the cube root. Take the cube root of both sides of the equation.

`\sqrt[3]{216 yd^3}=\sqrt[3]{s^3}`

`\sqrt[3]{216yd^3}=s`

`6yd=6`

The side length of the cube is 6 yards.

Answer 2

6 yards

Explanation:

a³ = 216

a = ∛ 216

= 6 yards
