Estimate the weight of water in pounds in a fish tank with width 14 ft, length 32 ft, and height 24 ft. The density of water is about 8.33 pounds per gallon. One gallon of water is approximately 0.134 cubic feet. Round to the nearest tenth.

A: 668,389.3 lbs
B: 9,632 lbs
C: 80,238.8 lbs

Respuesta :

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
