Answer:

158 cm²

Step-by-step explanation:

Given dimensions of the right rectangular prism:

  • length (l) = 8 cm
  • width (w) = 3 cm
  • height (h) = 5 cm

Surface area = 2(wl + hl + hw)

                      = 2(3 × 8 + 5 × 8 + 5 × 3)

                      = 2(24 + 40 + 15)

                      = 2(79)

                      = 158 cm²
