There are 2 triangles.

Area of a triangle is 1/2 x base x height = 1/2 x 4 x 3 = 6 square units each.

6 x 2 = 12 square units.

There is 1 rectangle 3 x 10 = 30 square units.

There is 1 rectangle 5 x 10 = 50 square units.

5 is the hypotenuse of the triangle found by using the Pythagorean theorem.

There is 1 rectangle 4 x 10 = 40 square units.

Total surface area = 12 + 30 + 50 + 40 = 132 square units.
