Identify the formula for the volume of a cube, which is given by \(V = s^3\), where \(s\) is the length of one side of the cube.
Calculate the volume in cubic inches by cubing the side length: \(V = (12.5)^3\) inches\(^3\).
Recall the conversion factor between inches and centimeters: \(1 \text{ inch} = 2.54 \text{ cm}\).
Convert the volume from cubic inches to cubic centimeters by using the conversion factor cubed: \(1 \text{ inch}^3 = (2.54)^3 \text{ cm}^3\).
Multiply the volume in cubic inches by \((2.54)^3\) to get the volume in cubic centimeters: \(V_{cm^3} = V_{in^3} \times (2.54)^3\).
