Answer:

612 cm²

Explanation:

Total surface area = area of all the nets in that make up the shape

✔️There are 2 equal rectangles of the following dimensions:

L = 10 cm

W = 4 cm

Area = 2(10*4) = 80 cm²

✔️There are 2 equal rectangles of the following dimensions:

L = 10 cm

W = 17 cm

Area = 2(10*17) = 340 cm²

✔️There are 2 equal rectangles of the following dimensions:

L = 4 cm

W = 17 cm

Area = 2(17*4) = 136 cm²

✅Total surface area = 80 + 340 + 136 = 612 cm²
