Can somebody help me find the surface area of this

Answer:
G. 7600 [tex]cm^{2}[/tex]
Step-by-step explanation:
Step 1: Deconstruct the shape
2 rectangles with dimension of 50 cm x 20 cm
2 rectangles with dimension of 40 cm x 20 cm
2 rectangles with dimension of 40 cm x 50 cm
Step 2: Find surface area of the shapes
2(50 x 20) = 2000 [tex]cm^{2}[/tex]
2(40 x 20) = 1600 [tex]cm^{2}[/tex]
2(40 x 50) = 4000 [tex]cm^{2}[/tex]
Step 3: Add the surface areas together
2000 + 1600 + 4000 = 7600 [tex]cm^{2}[/tex]
Therefore the surface area is 7600 [tex]cm^{2}[/tex] and the answer is G.
