Eric is incorrect because since the numbers he rounded 28 and 48 to are greater than 28 and 48 the answer to 28*48 will be less than the answer to 30*50 was.
30*50 = 1500
28*48 = 1344
Hope that helps!! :D

Answer:
491,400 ft·lb
Step-by-step explanation:
The mass of the water is ...
M = Vρ = LWHρ = (25 ft)(15 ft)(7 ft)(62.4 lb/ft³) = 163,800 lb
The average depth is 3 ft, so the work required is equivalent to that required to raise this mass 3 ft.
W = (3 ft)(163,800 lb) = 491,400 ft·lb
