How much larger is the volume of a cube with a side length of 18 feet long than a cube with a side length of 10 feet long? The larger cube is cubic feet bigger in volume than the smaller cube.

The volume of a cube is calculated by taking the side length and cubing it.

For the cube with a side length of 18 feet:
Volume = 18^3 = 5832 cubic feet

For the cube with a side length of 10 feet:
Volume = 10^3 = 1000 cubic feet

The difference in volume between the two cubes is:
5832 - 1000 = 4832 cubic feet

Therefore, the larger cube is 4832 cubic feet bigger in volume than the smaller cube.
