8 Feet Length
3 Feet Wide
1.5 Feet Deep
thats what you put
to me length is different than hieght but depth is the same almost.
hieght explains how far up something goes and depth is how far down

damn dude sounds like youll just barely fit in there with a 3 foot ass and a 1.5 foot dick
hehe :-)
no but really just get fresh air in and stale air out
it doesnt need to be that powerfull in that small of a space
