Fb=volume*density air
= 1200N/densitywater * density air
= 1200N*density air/density water
density water= 1e3kg/m^3
density air= about 1.225 kg/m3
Fb=1200N*(1.224/1e3)=1.2*1.224 N
check my figuring
Estimate the buoyant force that air exerts on you. (To do this, you can estimate your volume by knowing your weight and by assuming that your weight density is a bit less than that of water.) Assume that your weight is a about 1200N.
