Here is the problem:
An auditorium measures 40.0m X 20.0m X 12.0m. the density of the air is 1.20kg/m^3.
a) what is the volume in cubic ft?
b) the weight of the air in the room in pounds.
for a) i have some big answer. 339020 ft^3. using V=l*w*h and then using basic dimensional analysis to convert from cubic meters to cubic ft. (my answer in metric was 9600m^3.
for b) i have no clue how to convert a density to a weight.
any pointers or suggestions would be great.
TIA...
