Answer 2

Density is the mass per unit volume.
Density = mass / volume
density of water is 8.33 lbs per gallon.
the volume of tank - height x width x length = 24 ft x 14 ft x 32 ft = 10 752 ft³
1 gallon is equivalent to 0.134 ft³
therefore 0.134 ft³ has a weight of 8.33 lbs
then 10 752 ft³ has a weight of - 8.33/ 0.134 x 10752 = 668 389.3 lbs
answer is A
