## Jon93c 3 years ago Geometry help please Malcolm bought a square sheet of paper of side 16 inches to decorate a pencil box he made in craft class. The pencil box has a height of 7 inches, a width of 4 inches, and a length of 5 inches. Approximately how many square inches of paper will be remaining if he pastes paper on to the bottom base and the four side surfaces of the pencil box without any overlap?

1. hoblos

area of paper = 16^2 =256 in^2 area to be covered = 2(7*4 + 7*5) + 4*5 = 146 in^2 remaining part = 256-146 = 110 in^2

2. Mertsj

Bottom: 2(4 X 5)=40 front and back: 2(4 X 7)=56 right side and left side: 2(5 X 7)=70 Total: 40+56+70=146 Total sheet = 16X16 = 256 Left over: 256-146=110

just had to point out that you said 70+56+40=146....it doesn't..it equals 166...that changes the answer to 90

but the answer is 110 becuase it does not say include the top..but the math was wrong
