I think these are the only conversion factors needed, I dont have trouble doing the conversion of units, rather the question it self. Cant make sense of it, any help appreciated. How do I work out the depth, if I dont know the height of the cylinder.A cylindrical fuel storage tank has a diameter of 13 ft. The fuel stored in the tank has a density of $\displaystyle 0.80 g cm^{-3} $ and is used in a furnace at a rate of 2.95 lbm per minute. If the depth of fuel in the tank is initially 18.7 ft, what is the depth of fuel in the tank after the furnace has been running for three days? Express your answer in meters.

Thanks

1 ft = 0.304m

1000 g = 2.205 lbm
