Cody is painting the front door of his house. The dimensions of the door are 80 inches by 36 inches by 2 inches. If he paints all of the surfaces, how much area will he paint?
Accepted Solution
A:
To find out how much area he will paint, you will find the area of all 6 faces.
Each face is in the shape of a rectangle, so use A = lw as your formula.
Front/Back: 80 x 36 = 2880 square inches 2880 square inches x 2 = 5760 square inches
Right/Left Sides: 80 x 2 = 160 square inches 160 square inches x 2 = 320 square inches
Top/Bottom: 36 x 2 = 72 square inches 72 square inches x 2 = 144 square inches
