Your friend of mass 150 can just barely float in fresh water. Find her volume.
You must provide the units of her weight as well as a number. Is it pounds?
If she "barely floats", her volume is the same as that of an equal mass of liquid water.
Water weighs 62.4 lb/ft^3
150 lb of water would occupy 2.40 ft^3
