Question

When Tyson opens and lays a cereal box out flat, he sees that the top and the bottom of the box both measure 11 inches by 8 inches, the sides of the box both measure 11 inches by 6 inches, and the front and back of the box both measure 8 inches by 6 inches. What is the surface area of Tyson’s cereal box?

Answer 1

Hello!

A cereal box is a rectangular prism

The equation to find the surface area of a rectangular prism is

2(wl + wh + lh)

The length is 11
The width is 8
The height is 6

Put in the values

2(8 * 11 + 8 * 6 + 11 * 6)

Multiply

2(88 + 48 + 66)

Add

2(202)

Multiply

404

The answer is 404 inches squared

Hope this helps!
