The diagram is a net right rectangular pyramid. Calculate the total surface area
208cm2
112cm2
92cm2
76cm2
Correct answer is C
Total surface area = sum of the area of the △ S + Area of the rectangle
= 2 x Area of △ PTQ + 2 x Area of △ QUR + Area of rectangle PQRS
2 x 12(8 x 4) + 2 x 12(5 x 4) + 8 x 5
= 32 + 20 + 40
= 92cm2
