Assume the World weighs One Trillion Tons (Imperial).
A wall is built around the circumference of the globe (using the same value, i.e. 4,000 miles).
The wall uses bricks of 9" in length and 4.5" in height to an overall height of 6 feet.
Each bricks weighs 5 lbs.
How much does the Earth weigh AFTER the material for the bricks has been removed?
Marts
well if you build a wall around the earth using material from the earth, then the total mass would not change...
didn't take long to solve this un did it marts?
