Question

Roman is shipping a cardboard box that is a rectangular prism. The net of Roman's box is shown. What is the area of cardboard, in square inches, required for Roman's box?

Answer 1

The surface area is 248 square inches

Explanation:

The missing dimensions (that complete the question) are:

`Length = 4\ in` --- L

`Width = 6\ in` ---- W

`Height =10\ in` --- H

Required:

Calculate the surface area

The surface area is:

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

Substitute values for L, W and H

`Area = 2(4*6+ 4*10 + 10*6)`

`Area = 2(24+ 40 + 60)`

`Area = 2(124)`

Remove bracket

`Area = 2*124`

`Area = 248`
