Question

13. What is the surface area of the rectangular solid below using its net?

90 square units
108 square units
72 square units
84 square units

Answer 1

108 square units

Explanation:

3 x 4 = 12

3 x 4 = 12

6 x 3 = 18

6 x 3 = 18

6 x 4 = 24

6 x 4 = 24

24(2) + 18(2) + 12(2) = 108 square units

Therefore, the surface area of the rectangular solid below using its net is 108 square units
