A gambling casino is designed in the shape of a square pyramid with a side length of 60 ft. The height of the building is 36 ft. An air filtering system can circulate air at 14,400 cu ft/hr. How long will it take the system to filter all the air in the room

Therefore the system will take 9 hours to filter all the air in the building.

Step-by-step explanation:

Given that,

a gambling casino in the shape of squared pyramid with a side length of 60 ft.

The height of the building is 36 ft.

The volume of the building is =  Area of the base ×height

                                                 = (60²×36) cubic ft

The volume of the air in the building =  The volume of the building.

                                                             = (60²×36) cubic ft

An air filtering system can circulate air at 14,400 cubic ft per hour.

It means

The air filtering system can circulate 14,400 cubic ft air in    1    hour.

The air filtering system can circulate      1      cubic ft air in     hour.

The air filtering system can circulate (60²×36) cubic ft air in     hours.

                                                                                                  = 9 hours.

Therefore the system will take 9 hours to filter all the air in the building.

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
