Trouble finding tank demensions

[Saltybubbles288]

I am purchasing a used tank today and I'm trying to find out what it's demensions I was told it was a 100 gallon but it is much taller than any demensions I could find, possibly a 93 cube? I'm guessing it's 36x36x42 though I can be way off. Any more experienced hobist have a guess on the demensions?

Why don't you ask him to give you the dimensions for it?
