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] Surface Area = (one-half) (5) (12) + (5) (10) + (12) (10) + (13) (10) Surface Area = (one-half) (5) (13) + (one-half) (5) (13) + (13) (10) + (12) (10) Surface Area = (2) (5) (13) + (5) (10) + (13) (10) + (12) (10) Surface Area = (one-half) (5) (12) + (one-half) (5) (12) + (5) (10) + (12) (10) + (13) (10)
