We need to find the surface area of the rectangular prism, we are going to use the next formula:
Surface Area of Rectangular Prism:
S = 2(lw + lh + wh)
So the front/back = 4 * 2.2 = 8.8
The rigth/ left = 2.2 * 2.7 = 5.94
and the botton/ top = 4* 2.7= 10.8
S = 2 ( 8.8 + 5.94 + 10.8)
S = (2* 8.8) + (2*5.94) + (2*10.8)
S = 51.08 in^2
The correct option is D.
