Question

A box has dimensions of 19 inches long, 1.7 feet wide, and 6 inches high. What is the volume of the box?

Answer 1

1) Change 1.7 feet into inches so we get all the same units of inches
1.7 feet = 20.4 in (you multiply 1.7 by 12 to get the inches since 1 foot = 12 in)
2) Multiply all the numbers (since they now have the same unit)
19 x 20.4 x 6 = 2325.6
3) add the unit which is inches
ANSWER: 2325.6 in^3

Answer 2

Multiply 1.7 feet by 12 to change to inches:

1.7 x 12 = 20.4 inches

Now multiply the 3 dimensions:

19 x 6 x 20.4 = 2325.6 cubic inches

If you need cubic feet divide cubic inches by 1728:

2325.6 / 1728 = 1.36 cubic feet.
