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

From Ken: 10 friends run into each other at a bar. We will name them A,B,C,D,E,F,G,H,I AND J.
They all leave at the same time heading for seperate bars. However, A runs into B, C runs into D, E runs into F, G runs into H and I runs into J. These five groups leave again and the same thing keeps happening, but each time running in to someone they have not run into before. How many bars will it take, with each person meeting the others only once, until all of them have met each other again? Answered by Chris Fisher. |
