Question

The dimensions of the open truck bed on Jim's pick-up truck are shown in the figure below.

Jim wants to paint the inside of the truck bed. What area will he paint?

Answer 1

Do you use the surface area formula?

Answer 2

just the inside... so you're basically finding the surface area of the prism MINUS (69)*(80.25)

Answer 3

Why minus?

Answer 4

Because of the inside?

Answer 5

The answer is 12,104.25, just throwing that out there.

Answer 6

2*(22*69) + 2*(22*82.25) + 1*(69*82.25)
you don't paint that top part because it's like an open box....
