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
