How much larger is a cube with a side length of 18 feet long than a cube of a side length of 14 feet long?

To find the difference in volume between the two cubes, we first need to calculate the volume of each cube.

The volume of a cube is given by V = s^3, where s is the side length of the cube.

For the cube with a side length of 18 feet: V1 = 18^3 = 5832 cubic feet
For the cube with a side length of 14 feet: V2 = 14^3 = 2744 cubic feet

Now, we can find the difference in volume: V1 - V2 = 5832 - 2744 = 3088 cubic feet

Therefore, the cube with a side length of 18 feet is 3088 cubic feet larger than the cube with a side length of 14 feet.
