A cube measures 12.5 inches on each side. What is its volume in cubic centimeters?
A
31,900 cm^3
B
3,200 cm^3
C
1,980 cm^3
D
4,900 cm^3
Verified step by step guidance1
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: \(V_{cm^3} = V_{in^3} \times (2.54)^3\).
