Solution :

density=mass/volume

62.4lbm/ft^3=mass/2ft^3

mass=124.8lbm

w=mg

=124.8lbm*32.174ft/s^2

=4.015*10^3lbf (sea level)

w=mg

=124.8lbm*32.139ft/s^2

=4.011*10^3lbf (Colorado)

is that correct?

One lbm is equivalent to about 0.454 kg. One lbm also has a weight of one pound force when g = 32.174 ft/s^2.

I'll stick to metric, it's so much easier.

So its the ratio 32.139:32.174 that gives the value of g. That makes much more sense.
