Question 969350: If a rectangular box is 12 wide,15 inches long and 9 inches high. How many square inches of paper do I need to cover the surface of the box. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! There are six surfaces, and drawing a picture is essential to solving this problem. There are three pairs, the top/bottom; the ends; the sides.
The top and bottom are length X width and that would be 2* (12 *15 )=360 in^2
The two ends are width X height and that would be 2 * ( 9 * 12)= 216 in^2
The two sides are length x height and that would be 2*(15 * 9)=270 in^2
Total is the sum or 846 in^2
