Complete Question:
A pedestal for a statue is made with 405 cubic feet of concrete. A rectangular prism with a height of 9 feet.
What is the area of the base of the pedestal?

To find the area of the base of the pedestal;
Volume of pedestal = base area * height
405 = base area * 9
Base area = 405/9
Base area = 45 square feet.
Therefore, the area of the base of the pedestal is 45 square feet.
Answer:
45 square feet

!. Scale factor = 5
2. Scale factor = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
scale = [tex]\frac{length in drawing}{actual length}[/tex]
1. To increase the numbers, let the scale factor be [tex]\frac{5}{1}[/tex] = 5. So that;
0.05 x 5 = 0.25
[tex]\frac{1}{2}[/tex] x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be [tex]\frac{1}{5}[/tex]. So that;
0.05 x [tex]\frac{1}{5}[/tex] = 0.01
[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{5}[/tex] = 0.5 x [tex]\frac{1}{5}[/tex] = 0.10
7 x [tex]\frac{1}{5}[/tex] = 1.40
13 x [tex]\frac{1}{5}[/tex] = 2.60
25 x [tex]\frac{1}{5}[/tex] = 5.00
102 x [tex]\frac{1}{5}[/tex] = 20.40
