how to calculate cbm from length width and height?
To find the CBM, use the standard formula for volume and multiply the length, width, and height of the rectangular prism. For example, say the length is 5.5 meters, the width is 2.5 meters, and the height is 7.0 meters: 5.5 x 2.5 x 7.0 = 96.25, so the CBM is 96.25 cubic meters.
