HELP NEEDED NOT HARD 5 PTS

You are renting a moving truck and need to find one with
enough space to carry your furniture. All the trucks are 7 feet
tall and 6 feet wide, but the lengths vary.
You need a truck with a volume of 840 cubic feet. Use the
volume of a rectangular prism formula V lwh to find the
length of the truck you need?

Answer:

20 Feet

Explanation:

If the trucks are all 7 feet tall, and 6 feet wide, then we can find out how long we need the truck to be by using this equation:

(l = length)

7 × 6 x l = 840

Or we can simply multiply 6 and 7 then divide 840 by that number.

6 × 7 = 42

840 ÷ 42 = 20

The truck would need to be 20 feet long to carry all of your furniture.
