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.
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.
