Final answer:
To find the edge length of a cube with a volume of 8 cubic feet, take the cube root of 8, which is 2. Hence, the edge length of the cube is 2 feet.
Step-by-step explanation:
The question is asking to find the edge length of a cubic shape given its volume. The volume of a cube is calculated by taking the edge length and raising it to the power of three (cubing it). For a cube with a volume of 8 cubic feet, one would take the cube root of 8 to find the edge length. The calculation is as follows: Cube root of 8 cubic feet is equal to 2 feet. Therefore, the edge length of the cube is 2 feet. This process of finding the cube root is fundamental in geometry when dealing with cubic shapes as it allows us to reverse the volume formula (V = edge length cubed) to find a missing dimension when the volume is known.
