I have this formula:
l*w*h (Length*width*height) = dimensional weight
if I have only width and height can I figure out length and find out weight? I am using getting my data from the Kinect to plug into the formula but it does not do length as far as I know.
On
(Length*width*height)=volume
http://en.wikipedia.org/wiki/Dimensional_weight
Dimensional weight is a calculation of a theoretical weight of a package. This theoretical weight is the weight of the package at a minimum density chosen by the freight carrier. If the package is below this minimum density, then the actual weight is irrelevant as the freight carrier will charge for the volume of the package as if it were of the chosen density (what the package would weigh at the minimum density).
You have one equation in two unknowns, so will not be able to find a solution without another piece of data.
