Answer:
The surface area is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The surface area of a triangular prism is equal to

where
B is the area of the triangular base
P is the perimeter of the triangular face
H is the height of the prism
<em>Find the area of the base B</em>

<em>Find the perimeter of the base P</em>

we have

substitute the values
The surface area is

Answer: 36
Step-by-step: 6 2/3 + 5 1/3 = 12
12 x 3 = 36
Answer:

Step-by-step explanation:
Answer:
c=3
Step-by-step explanation:
4c+12-2c=5c-3 1. combine like terms
2c+12=5c-3 2. -5c on both sides
-3c+12=3 3. -12 on both sides
-3c=-9 4. /-3 on both sides
c=3
