How much does a glass weigh?

Question

How much does a 2x2 meter plastic glass weigh?....it felt actually like 400 to 600 pounds...but more precicely?

Answer 1

If by "glass" you are referring to a "tumbler," there are several factors that need to be taken into consideration:

What kind of plastic?

Is in empty or does it contain something?

If it contains something, what?

If it contains something, how full is it?

What is it's capacity?

BTW: That would be a VERY LARGE tumbler!

Answer 2

Depends on the type of plastic, the thickness and the density of the plastic.
