A cubic foot is a cube with each side measuring 1 foot. Since 1 foot = 12 inches, each side also measures 12 inches. How many cubic inches are contained in 1 cubic foot?
Correct Answer
1,728 in³
Explanation
Each level of the cubic foot contains 12 × 12 = 144 cubic inches, and the cubic foot has 12 levels. Using multiplication to count the total number of cubic inches:
\[12 \times 12 \times 12 = 1{,}728\]
There are 1,728 cubic inches in 1 cubic foot. Thus, \(1 \text{ ft}^3 = 1{,}728 \text{ in}^3\).
