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?

To find the volume of a cube, you cube the length of one of its sides.

For the cube with a side length of 18 feet, the volume would be:
Volume = (18 feet)^3 = 5832 cubic feet

For the cube with a side length of 10 feet, the volume would be:
Volume = (10 feet)^3 = 1000 cubic feet

To find how much larger the volume of the 18-foot cube is compared to the 10-foot cube, we subtract the volume of the 10-foot cube from the volume of the 18-foot cube:
5832 cubic feet - 1000 cubic feet = 4832 cubic feet

Therefore, the volume of the cube with a side length of 18 feet is 4832 cubic feet larger than the volume of the cube with a side length of 10 feet.
