Final answer:
To find the length of an edge of a cube with a volume of 216 cubic inches, calculate the cube root of the volume, which gives an edge length of 6 inches.
Step-by-step explanation:
To find the length of an edge of a storage cube with a volume of 216 cubic inches, we can use the formula for the volume of a cube, which is:
volume of cube = edge length × edge length × edge length, or
edge length³ = volume of cube.
To find the edge length, we take the cube root of the volume:
edge length = √³(volume of cube).
In this case:
edge length = √³(216 cubic inches).
Calculating the cube root of 216:
edge length = 6 inches.
Therefore, each edge of the cube is 6 inches long.
