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.
Something that could be done is to tie a rope long enough to cross the river and send the two younger brothers across first, then have Mike pull the boat back across the river with the rope and him get in the boat and row it across the river with just himself and the gear.
Another option is you can unload some gear, put the boys in the boat, row them across the river, unload the two younger boys, go back for the rest of gear and load it into the boat then come back.
Hope this helps!
