I didn't understand your question.
Answer:
208 square inches of cardboard.
Step-by-step explanation:
We have been given that Connie is making a cardboard ice-cream truck for a school project. The truck is 8 inches long, 4 inches wide, and 6 inches tall. We are asked to find the amount of cardboard used by Connie to make the truck.
We will use surface area of cuboid to solve our given problem.
![\text{Surface area of cuboid}=2(lw+wh+hl)](https://tex.z-dn.net/?f=%5Ctext%7BSurface%20area%20of%20cuboid%7D%3D2%28lw%2Bwh%2Bhl%29)
Upon substituting our given values in above formula, we will get:
![\text{Amount of card-board needed}=2(8\cdot 4+4\cdot 6+6\cdot 8)](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20card-board%20needed%7D%3D2%288%5Ccdot%204%2B4%5Ccdot%206%2B6%5Ccdot%208%29)
![\text{Amount of card-board needed}=2(32+24+48)](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20card-board%20needed%7D%3D2%2832%2B24%2B48%29)
![\text{Amount of card-board needed}=2(104)](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20card-board%20needed%7D%3D2%28104%29)
![\text{Amount of card-board needed}=208](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20card-board%20needed%7D%3D208)
Therefore, Connie needs 208 square inches of cardboard.
