Question

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.

Answer 1

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

Answer 2

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

Complete Question:

[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)

See attachment for the figure.

Explanation:

The surface area of the rectangular prism is:

`A_(s) = (1)/(2)\cdot (5\,cm)\cdot (12\,cm) + (10\,cm)\cdot (13\,cm) + (10\,cm) \cdot (12\,cm) + (10\,cm)\cdot (5\,cm)\\`

`A_(s) = 330\,cm^(2)`

Hence, the answer is A.
