Answer:

336

Step-by-step explanation:

We know that a cube has 6 faces which means we can use this equation:

56 x 6 = 336

336 square inches is the answer.

Perimeter=56in

  • Side=56)4=14in

So area of one side=

  • (side)^2=(14)^2=196in^2

Cube has 6sides

So total protection:-

  • 6(196)
  • 1176in^2
