Answer:
The surface area is 78 unit square.
Step-by-step explanation:
Given : The surface area for a rectangular prism with a square base is 
.
To find : What is the surface area if s=3 and h=5?
Solution :
The surface area for a rectangular prism with a square base is
Substitute, s=3 and h=5
Therefore, The surface area is 78 unit square.
You would multiply it by 4
4(3x^2 +2 )
12x^2 +8
The four quadrants and the sign of coordinates is given as follows:
Quadrant I : (n, n ) both x and y positive.
Quadrant II : ( -n,n) = x negative and y positive.
Quadrant III : ( -n,-n) = both x and y negative.
Quadrant IV: (n, -n) = x positive and y negative.
So Based on the above concept , we can say that vertex C (-n,-n) has both x and y negative and so it lies in quadrant III.
Answer is Vertex C (-n,-n)
