The answer to your question is c
Answer:factor of 9
Step-by-step explanation:
Given
prism were changed by a scale factor of 3
Suppose prism is rectangular in shape
So surface are is 
Where l=length
w=width
b=breadth
So new length,breadth and width is






So new surface area would change by a factor of 9
Answer:
V = 13312yd^2
Step-by-step explanation:
32 x 32 x 39 / 3 = volume
32 x 32 x 39 = 39936/3 = 13312 sq yard.
As you can see the formula for Volume is L x W x H / 3
The formula for Area of a pyramid is SA = A + (3/2)bh
We have one rule we work out the square to represent the A then we can find SA. While 3/2 is 1.5 really which is 150% of the height x the base, then we + plus the area of the square.
