Kristen is wrapping presents for the holidays. she has a box that measures 4 ft. x 2 ft. x 2 ft. how many square feet of wrapping paper does she need to cover the box without overlapping?

You first find the area of one piece. The small squares are 4 and there are two so you have 8 so far. The length of the rectangles are 4 and using the width of the square (2) and you multiply, then you get 8 per rectangle, there are 4 rectangles so the total area of the rectangles are 32 adding the 8 from the squares, you get 40 square feet. (2*2*2)+(4*2*4)=40 square feet. Hope this helped!

He is right i did this thing before
