Answer:

1080

Explanation:

The surface area is the sum of the areas of the faces.

This L-shaped prism has 8 faces: the 2 Ls on the ends, and the 6 rectangular faces along the sides of the L.

The area of each L is 14×10 − 10×8 = 60.

The total surface area is therefore:

A = 2(60) + 20×4 + 20×8 + 20×10 + 20×2 + 20×14 + 20×10

A = 1080

The surface area is 1080 cm².
