Terrarium in gallons?

[cath1024]

Hi there,
I just bought a new tank for one of my BD's and was wondering how i can find out the size of it in gallons?
The measurements are 39" long 19.5 high and 18.5 wide.
I have my young female in a 31? long 19.5 high 18.5 wide

If anyone could let me know or how to convert these that would be great
Thank you!
