What is the volume of a cube with an edge length of 2.5 ft.? Use the formula for the volume of a cube..

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

Given that the edge length (s) of the cube is 2.5 ft, we can substitute this value into the formula:

V = (2.5 ft)^3
V = 2.5 ft x 2.5 ft x 2.5 ft
V = 15.625 ft^3

Therefore, the volume of a cube with an edge length of 2.5 ft is 15.625 cubic feet.
