Which equation can be used to calculate the surface area of the triangular prism net show below?

The net of a rectangular prism. The rectangular sides are 10 centimeters by 13 centimeters, 10 centimeters by 12 centimeters, and 10 centimeters by 5 centimeters. The triangular sides have a base of 5 centimeters and height of 12 centimeters.

[Not drawn to scale]

a
Surface Area = (one-half) (5) (12) + (5) (10) + (12) (10) + (13) (10)

b
Surface Area = (one-half) (5) (13) + (one-half) (5) (13) + (13) (10) + (12) (10)

c
Surface Area = (2) (5) (13) + (5) (10) + (13) (10) + (12) (10)

d
Surface Area = (one-half) (5) (12) + (one-half) (5) (12) + (5) (10) + (12) (10) + (13) (10)

Answer:

a. [tex]A_{s} = \frac{1}{2}\cdot (5\,cm)\cdot (12\,cm) + (10\,cm)\cdot (13\,cm) + (10\,cm) \cdot (12\,cm) + (10\,cm)\cdot (5\,cm)[/tex]

Step-by-step explanation:

The surface area of the rectangular prism is:

[tex]A_{s} = \frac{1}{2}\cdot (5\,cm)\cdot (12\,cm) + (10\,cm)\cdot (13\,cm) + (10\,cm) \cdot (12\,cm) + (10\,cm)\cdot (5\,cm)[/tex]

[tex]A_{s} = 330\,cm^{2}[/tex]

Hence, the answer is A.
