Question

Connie is making a cardboard ice-cream truck for a school project. She painted the body of the truck on a cardboard template. How much cardboard did Connie use if the truck is 8 inches long, 4 inches wide, and 6 inches tall?

Answer 1

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

Answer 2

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.

$\text{Surface area of cuboid}=2(lw+wh+hl)$

Upon substituting our given values in above formula, we will get:

$\text{Amount of card-board needed}=2(8\cdot 4+4\cdot 6+6\cdot 8)$

$\text{Amount of card-board needed}=2(32+24+48)$

$\text{Amount of card-board needed}=2(104)$

$\text{Amount of card-board needed}=208$

Therefore, Connie needs 208 square inches of cardboard.
