The two horizontal lines are parallel.
This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.
This means x + 20 needs to equal 80.
X = 80-20 = 60 degrees.
The top and bottom faces are 3 inches by 3 inches.
Area = 3 in. * 3 in. * 2 = 18 in.^2
The front, back, right, and left faces are 3 in. by 6 in.
Area = 3 in. * 6 in. * 4 = 72 in.^2
Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2
Answer: B. 90 square inches
D = 20
