To get the total volume of a volume ROI (ones in ROI, zeros elsewhere), use wb_command -volume-weighted-stats with -sum, as this uses voxel volume as the weights.
I suppose you could get gray matter volume per voxel by using -volume-math to multiply a gray matter mask by the cube of the voxel resolution. You'll probably need to use -volume-math and the freesurfer segmentation to get the gray matter mask.
