Can a certain rectangular sheet of glass

Can a certain rectangular sheet of glass be positioned on a rectangular tabletop so that it covers the entire table top and its edges are parallel to the edges of the tabletop?

3 Explanations



Statement II is worded as "the area of one side of the sheet of glass". What does it exactly mean? Of course area of a rectangle is length times width then why is there a need to write the statement in such a way?

Hi Jia,

That's a great question! What you've said is correct - the statement should be obvious if we just say "the area of the sheet of glass."

However, a sheet of glass has 3 dimensions (that is, it has a thickness as well). This is probably why the test writers chose to word the question that way, so that they could avoid any confusion.

I hope that helps!

Hi Rob :)

It looks like the OG question you've provided the link to doesn't match up with this question. Did you mean to include the link for a different question?
