Answer:

  5 gallons

Step-by-step explanation:

The container volume can be found from the formula for the volume of a cylinder:

  V = πr^2h

  V = π(6 in)^2(10 in) = 360π in^3 ≈ 1130.97 in^3

Then the number of gallons is ...

  (1130.97 in^3)/(231 in^3/gal) = 4.896 gal

The approximate volume of sand is 5 gallons.
