the Ohio Department of Transportation wants to weigh down its cones with sand to keep the wind from knocking them over. The bottom of the cone is 11 inches across and has a height of 12 inches. How much sand will be needed to fill it? What is the answer? And how did you get that answer?

1. The sand will all run out - the cones have no bottom so they can be stacked otherwise google "volume of cone formula"
