Answer:
144 u²
Step-by-step explanation:
first we need to find lateral area
La=Ph
LA=(12)(11)
LA= 132 u²
SA= Ph + 2B
SA= 132 + 2(6)
SA= 144 u²
For this case we have to, by definition:

This means that, the cosine of the angle F, will be equal to the leg adjacent to the angle on the hypotenuse of the triangle.
So, by clearing h we have:

Rounding out the value of h we have:

9 Ibs(pounds) + 6 oz(ounces) ⇒ ounces
First, let's find out how many 1 pound is equal to in ounces.

Since 1 pound is equal to 16 ounces, multiply the 9 pounds by 16.
