Cubic yards of trash 2006-08-23
From Chris:

I am journalist in California trying to convert cubic yards of trash (appliances, furniture, tires and household trash) into the space of a football field.

Is there a formula for this?

For example, how much of an American football field would 45,000 cubic yards of said trash fill up? The typical American football field I am told is 120 yards (110 meters) long by 53 1/2 yards (49 meters) wide

Ideally, I'd like to be about to say this amount of trash would fill up the football field XX-feet deep

However, A runs into B, C runs into D, E runs into F, G runs into H and I runs into J.
