6.7 square feet
22.5 square feet

Answer 1

45

Explanation:

Answer 2

45 square feet

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`
