ANSWER
The area of the floor is 696 square feet.
EXPLANATION
It was given that, the volume inside a rectangular storage room is 2,088 cubic feet.
The rectangular room is a rectangular prism.
The volume of a rectangular prism is
[tex]V = floor \: area \times height[/tex]
The height of the room is 3 ft.
This implies that,
[tex]2088= floor \: area \times3[/tex]
Divide both sides by 3.
[tex] \frac{2088}{3} = floor \: area [/tex]
[tex]floor \: area = 696 {ft}^{2} [/tex]
The area of the floor is 696 square feet.
