Joe wants to wrap a present for his mom the box is a rectangular prism with sides 5.6 cm, 7.9 cm and 8.6 cm if Joe doesn't want to waste any paper how much paper will he need?

160.34 cm2 of paper

Step-by-step explanation:

To know how much paper Joe will need, we need to find the total area of the rectangular prism.

The prism has 6 faces, and their areas are:

face 1 and 2: 5.6 cm * 7.9 cm = 44.24 cm2

face 3 and 4: 5.6 cm * 8.6 cm = 48.16 cm2

face 5 and 6: 8.6 cm * 7.9 cm = 67.94 cm2

The total area of the prism is:

Area = 44.24 + 48.16 + 67.94 = 160.34 cm2

So Joe will need 160.34 cm2 of paper.
