Question

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 10 inches, a width of 3 inches, and a height of 4 1/2 inches. What is the surface area?

Answer 1

The surface area is 177 square inches

Explanation:

Given

`Length = 10`

`Width = 3`

`Height = 4(1)/(2)`

Required

The surface area

This is calculated as:

`Area = 2 * (Length * Width + Length * Height + Width * Height)`

So, we have:

`Area = 2 * (10* 3+ 10* 4(1)/(2)+ 3* 4(1)/(2))`

`Area = 2 * (30+ 45+ 13(1)/(2))`

`Area = 2 * (88(1)/(2))`

`Area = 177`
