The gauge pressure in each of 4 car tires is 240kpa. If each tire has a footprint of 220cm^2 , what is the mass of the car?
Answered by drwls
Pgauge*(Footprint Area)*4 = M g

Solve for M.

The 4 is the assumed number of tires. This assumes the CM is midway between front and rear tires.

I get about 1980 kg. Make sure your area is in m^2.
