i have a cylinder that is 24" in diameter and 32" tall. it is filled with sand. what would the weigth of the sand be that is in the cylinder

Question

it is a lawn roller and we need to know what the total weight is including the sand

Answer 1

The volume of the cylinder is V = πr²h 

r = 1 foot

h = 2.67 ft

V = 8.39 cubic feet

 

Now, depending on the density of the sand, that will determine the mass or weight of the sand occupying 8.39 cubic feet. If you take dry sand as having a density of approximately 100 lb/cubic ft, then...

8.39 cubic ft x 100 lb/cubic ft = 839 pounds = weight of the sand.

 

One cannot calculate the weight of the roller because we don't know what it is made of.  Again, the same procedure could be used if you know the density of the material that the roller is made of.  Then just add that weight to the weight of the sand to get total weight.
