Answer:
72 cm^2
Step-by-step explanation:
How many surfaces are there?
Two 2 x 3 rectangles
Two 2 x 6 rectangles
Two 3 x 6 rectangles
Area of 2x3 rectangle = 6 cm^2
Area of 2x6 rectangle = 12 cm^2
Area of 3x6 rectangle = 18 cm^2
2(6) + 2(12) + 2(18) = Total Area of all the Surfaces or Surface Area
12 + 24 + 36 = 72 cm^2
