The correct answer is: 15.625

To determine the volume of a cube, you can use the formula $ V = s^3 $, where $ V $ represents the volume and $ s $ is the length of a side of the cube. In this case, the length of a side is 2.5 inches. First, you need to calculate $ (2.5)^3 $: 1. Calculate $ 2.5 \times 2.5 = 6.25 $. 2. Then, multiply that result by 2.5 again: $ 6.25 \times 2.5 = 15.625 $. Therefore, the volume of the cube is 15.625 cubic inches. This shows that the computed volume corresponds with the answer choice provided, making it the correct answer. Understanding the calculation process highlights that while other volume calculations might involve different shapes or dimensions, the cube's volume always specifically follows the rule of cubing the side length.
