Joseph wants to cover a rectangular box with wrapping paper. the length of the box is 2 feet, its width is 1 foot, and its height is 1 foot. the cost of wrapping paper is $0.80 per square foot. how much will it cost joseph to cover the box with wrapping paper?

We need to find the surface area of the box. For this, we will do 2(L×W) + 2(L×H) + 2(H×W); Since each has a corresponding side, we multiply it by 2.
Let's find it with plugging it in. 
2(2×1) + 2(2×1) + 2(1×1)
4+4+2=10
Now the surface area is 10 ft², let's just multiply .8 by that to find the price.
.8×10= 8
It'll cost $8 for Joseph to cover the box with wrapping paper.
Tell me if this helps!!
