I have grayscale .tif images which i have stored in a 3d array(volume0. I have binarized the 3D array. I wish to calculate the dimensions of dark color object in the 3D array.

I have grayscale .tif images which i have stored in a 3d array(volume). I have binarized the 3D array. I wish to calculate the dimensions of dark color objects in the 3D array. The dimension which i need are:
Location, Volume, Z-projection. I tried to use region props but it identifies a lot of small objects whivch are noise. I wish to only consider objects whose Z projection is above a certain value.

You should be able to use regionprops3() to get the 'volume', 'centroid' and 'image' properties. Take the 'image' property (a small volumetric image of the object itself), project it using any(...,3), and then calculate its area. I'm assuming that you're after the area of the projection.
