HELP!!!!! Need Measurment fast

[MamaPish]

I got the measurments the other day while at the LFS, they are 38x27x22

But I need to know the measurment from the back corner straight out to the front center....We are building a "built in cabinet for it today, and the LFS sold the one in stock...called another, and they were out of stock.......if you have one PLEASE measure it for me...THANKS!.......hubby is sawing and I think we may not have figured it right.
