Assuming you mean water weighs 62.4lb/ft^3, well -
5 x 3 x 2 = 30 ft^3
30 ft^3 x 62.4 lb/ft^3 = 1872 lb

assuming the water weighs that much per cubic foot...
5 ft x 3 ft x 2 ft = 30 cubic feet
30 cubic feet x 62.4 lbs = 1872 lbs.

Water: 62.4 lb/ft^3
5 * 3 * 2 = 30 ft^3
30 * 62.4 = 1872 lb

Well if it is 62.4 lbs per foot then find out how many feet total you have
5+3+2= 10ft
For every foot you add 62.4 (which is basically multiplying)
62.4 x 10 = 6240 lbs (Um, do a calculator check just to be sure)
