The volume of each floor is calculated as
Where l represents the lenght of the floor, w is for the width and h is the height.
You have the area of each floor, and also the height.
The area of the floor is caculated as
So if you use this equation in the first I gave to you, one can obtain this:
The volume for each floor is then calculated with the data you gave in the problem.
For example, for the first floor you have Area=25 ft. and Height=15 ft.
The volume of the first floor is then V=A*h=(25 ft.)*(15 ft.)=375 square feet
Calculating for the rest of the floors:

Then you calculate the total volume of the building, summing the volume column of the table.
The total volume of the building is 2430 square feet.
