the bottom of a shopping bag measures 8 inches by 10 inches and the height is 12 inches. how much paper is needed to make the bag?

(2) Answers

8 x 10 = 80. That is for the base. 12 x 10= 120. Times that by two because there are two sides that size so you get 240. 12x8=96. 96x2=192. You then need to add up all of the sides to get the total surface area. 80+240+192=512. 512 inches squared of paper is needed to make the bag.


First you multiply 8 by 10 to get 80 then you multiply that by 12 to get 960 inches cubed 960 inches cubed
