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.
[tex]\text{Surface area of cuboid}=2(lw+wh+hl)[/tex]
Upon substituting our given values in above formula, we will get:
[tex]\text{Amount of card-board needed}=2(8\cdot 4+4\cdot 6+6\cdot 8)[/tex]
[tex]\text{Amount of card-board needed}=2(32+24+48)[/tex]
[tex]\text{Amount of card-board needed}=2(104)[/tex]
[tex]\text{Amount of card-board needed}=208[/tex]
Therefore, Connie needs 208 square inches of cardboard.
Answer:
Step-by-step explanation:
length of the truck, l = 8 in
Width of the truck, w = 4 in
height of the truck, h = 6 in
The total surface area of the truck, S = 2 (l x w + w x h + h x l)
S = 2 (8 x 4 + 4 x 6 + 6 x 8)
S = 2 ( 32 + 24 + 48)
S = 208 in²
