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 one edge.
Plugging in s = 2.5 ft, we get:
V = (2.5 ft)^3
V = 2.5 ft * 2.5 ft * 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.
