1,904 ft2


1,860 ft2


3,764 ft2


14,280 ft2

Answer 1

The lateral surface area is: 1860 square feet

Explanation:

Given

The missing dimension are:

See attachment for storage

`L = 20` --- Length

`W = 42` --- Width

`H = 15` --- Height

Required

The lateral surface area

The lateral area is calculated as:

`Area = 2 * H * (L + W)`

So, we have:

`Area = 2 * 15 * (20 + 42)`

`Area = 30 * (20 + 42)`

`Area = 30 * 62`

`Area = 1860`
