### How to find pixel per meter

I have a static camera through which I am focusing on the covered area, total covered area by a camera is

length 78.7 cm
width 102.1 cm
heigh 118.5 cm


my image size is 800 * 480

now in the total covered area, I have another box whose

length is 22.6 cm
width is 25.6 cm
height is 24 cm


I want to find out how many pixels I have per meter. I am using the formula of

m/pixels * 0.39 but it's not giving the exact answer.
