Complete question;
A student draws the net below to show the dimensions of a container that is shaped like a right rectangular prism. What is the total surface area?
A. 19 B. 30 C. 38 D. 62
Attached is the image.
Step-by-step explanation:
Total surface area = Length × breadth
Total surface area is equal to the sum of surface area of section 1(main), surface area of section 2(wing) and surface area of section 3(wing).
TSA = SA1 + SA2 + SA3
TSA = 5×(2+3+2+3) + 3×2 + 3×2
TSA = 50 + 6 + 6
TSA = 62 ft^2
The total surface area is 62 ft^2
