Question

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

Answer 1

Answer:

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

Step-by-step explanation:

The surface area of the rectangular prism is:

$A_{s} = \frac{1}{2}\cdot (5\,cm)\cdot (12\,cm) + (10\,cm)\cdot (13\,cm) + (10\,cm) \cdot (12\,cm) + (10\,cm)\cdot (5\,cm)$

$A_{s} = 330\,cm^{2}$

Hence, the answer is A.
