Question
Concrete weighs 3,915 pounds per cubic yard. Calculate weight of a five gallon bucket of concrete(in pounds).

Thanks for your assistance.

Answer
I will assume that "gallon" refers to a U.S. fluid gallon.
5 gal = 0.0247556584 ydł
The bucket has a capacity of 0.0247556584 cubic yards.

0.0247556584 ydł × 3915 lb/ydł ≅ 96.92 lb
A five-gallon bucket of concrete weighs approximately 96.92 pounds. (Concrete is much denser than water. Five gallons of water weighs less than half as much.)
