A cereal manufacturer needs to order cardboard mateial for their cereal boxes. The length of the box is 8 inches, the width is 2 inches, and the height is 10 inches. Find th number of square inches the manufacturer needs to order for one box. Hint: Find the surface area of the box. Ignore necessary overlapping of the cardboard.

Answer 1

To find the surface area of the box, we need to find the area of each of the six faces and then add them up.

Surface area of one side = length * width = 8 * 2 = 16 square inches
Surface area of the other side = length * width = 8 * 2 = 16 square inches
Surface area of the top and bottom sides = length * height = 8 * 10 = 80 square inches
Surface area of the front and back sides = width * height = 2 * 10 = 20 square inches

Now, add up all the surface areas:
16 + 16 + 80 + 80 + 20 + 20 = 232 square inches

Therefore, the manufacturer needs to order 232 square inches of cardboard material for one box.
