Water weighs 64 pounds per cubic foot and there are 27 cubic feet in one cubic yard. So a cubic yard of seawater weighs 1728 pounds. The original VW Beetle weighed only 1650 pounds! If that seems hard to believe, consider that 1 cubic foot is almost 7.5 gallons, and a cubic yard is more than 201 gallons.
Â· just now. 1  One (1) cubic yard is: 3 feet x 3 feet x3 feet. The total cubic feet in a cubic yard is: 3 x 3 x 3 = 27. 2  1yrd=91.4364cm. 91.4364cm to the power of 3= 764464.99 cm3. 3  764.555 kg of water, at 4oC and 1 bar of pressure. The mass can vary, depending on temperature and pressure (the density of water changes with the change of temperature and pressure).
