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.
