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)
