Question

a building block in the shape of a cube was found in a toy box. it has side lengths of 2.5 inches. what is the volume of the building block, in cubic inches? provide an answer accurate to the nearest tenth.

Explanation:

Step1: Recall the volume formula for a cube

The volume \( V \) of a cube is given by \( V = s^{3} \), where \( s \) is the side - length of the cube.

Step2: Substitute the given side - length into the formula

Given \( s = 2.5 \) inches. Then \( V=(2.5)^{3}=2.5\times2.5\times2.5 \).
First, \( 2.5\times2.5 = 6.25 \). Then \( 6.25\times2.5=15.625 \).

Answer:

\( 15.6 \) cubic inches
