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

Answer:

The surface area is 248 square inches

Step-by-step 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

$Area = 2*124$

$Area = 248$
