How do i calculate width, length, and height into cubic feet?
Example 13" x 17" x 12 3/4".

Multiply the three together. As the lengths are in inches, divide the result by 1728. The answer is cubic feet.

If you're wondering, 1728 in the amount of cubic inches in one cubic foot (12^3).

13" * 17" * 12-3/4"
13 * 17 * (12 + (3 / 4))
13 * 17 * 12.75 = 2817.75 cubic inches / 1728 = 1.63 cubic feet

You can also convert the inches into feet before the calculation. In this case, don't divide by 1728 as the cubic measure is already in feet.

(13/12) * (17/12) * (12.75/12)
1.0833 * 1.4167 * 1.0625 = 1.63 cubic feet
