Step-by-step explanation:
The right trangular prism has 5 surface areas. 2 of them are triangles and 3 of them are rectangles.
Area of triangle
= 0.5(3/2)(2) = 3/2 square units.
Area of 1st rectangle
= (5/2)(5) = 25/2 square units.
Area of 2nd rectangle
= (3/2)(5) = 15/2 square units.
Area of 3rd rectangle
= (2)(5) = 10 square units.
Total Surface Area
= 2 * (3/2) + (25/2) + (15/2) + 10
= 33 square units. (A)
