cereal

13.5 in.

2.5 in.

8 in.

Total surface area?

Answer 1

323.5 square inches

Explanation:

The cereal box is not shown. However, the given details are enough to arrive at a solution

`Length = 13.5in`

`Width = 2.5in`

`Height = 8in`

Required

The total surface area (TSA)

This is calculated as:

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

`TSA = 2 * (13.5 * 2.5 + 13.5 * 8 + 2.5 * 8)`

`TSA = 2 * (161.75)`

`TSA = 323.5`

Hence, the total surface area is 323.5 square inches
