Question

what is the length of a tractor trailer if the volume of the trailer is 2000 cubic feet, the width is 7 feet 6 inches and the height is 9 feet 6 inches

Answer 1

To begin, make sure all measurements are expressed in the same units:

7 feet 6 inches = 7.5 feet
9 feet 6 inches = 9.5 feet

Next, recall the formula for volume:

V = L * W * H

Volume is length times width times height.  Plug in the values you know and solve for the length:

2000 = L * 7.5 * 9.5
2000 = L * 71.25
L = 2000 ÷ 71.25
L ≈ 28.07

Rounded to the nearest whole number, the length of the tractor trailer is 28 feet.
