Answer:
169
Step-by-step explanation:
The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.
(7) * (5) = (35)
(9) * (5) = (45)
(7) * (5) = (35)
() * (6) * (9) = (27)
() * (6) * (9) = (27)
Add up all of the values:
(35) + (45) + (35) + (27) + (27) = 169
