Answer:

45 square feet

Step-by-step explanation:

we know that

The volume of the pedestal (rectangular prism) is given by the formula

$V=Bh$

where

B is the area of the rectangular base of pedestal

we have

$V=405\ ft^3\\h=9\ ft$

substitute the given values in the formula and solve for B

$405=B(9)$

$B=405/9\\B=45\ ft^2$
