Answer 2

Answer:

D. 170.3 cm squared

Step-by-step explanation:

The formula for a surface area of a rectangular prism is  2(h x W) + 2(h x L) + 2(W x L)

length x width x height

height = h = 4.0 cm

width = W = 4.5 cm

length = L = 7.9 cm

2(4 x 4.5) + 2(4 x 7.9) + 2(4.5 x 7.9)

2(18) + 2(31.6) + 2(35.55)

36 + 63.2 + 71.1

170.3 cm squared
