What is the surface area of the right rectangular prism?

112 cm²

Step-by-step explanation:

The surface area is the sum of the area of all the 6 faces, that is

area = area of 2 purple  + area of 2 green + area of 2 orange

       = 2(4 × 8) + 2(2 × 8) + 2(4 × 2)

       = (2 × 32) + (2 × 16) + (2 × 8)

       = 64 + 32 + 16

       = 112 cm²
