Question

Been bought cell phone that came in a box shaped like a rectangular prism the box is 5 inches long by 3 inches wide by 2 inches high what is the surface area of the box

Answer 1

Answer: 62 in²

Explanation:

You must apply the formula for calculate the surface area of a rectangular prims, which is shown below:

`SA=2(wh+lw+lh)`

Where w is the width, l is the lenght and h is the height.

Based on the information given in the problem, you know that:

`l=5in\\w=3in\\h=2in`

Therefore, when you substitute these values into the formula, you obtain that the surface area of the rectangular prism is:

`SA=2[(3in*2in)+(5in*3in)+(5in*2in)]\\SA=62in^2`
