Question Figuring what a box is tuned to...

A friend of mine built the box I have but he is a carpenter and not a box builder so he really didn't know what he was doing as far as tuning goes so this is my question.

Can anyone tell me what my box is tuned to if I present the measurements?

Box:
L - 34"
W - 18"
H - 14"

Port:
L - 3"
W - 13.5"
H - 12.5"
