Measure two of the object's dimensions in meters. For an example, the object is a rectangular prism with a length of 8 meters and a width of 5 meters.
Multiply one measured dimension to the other. For this example, 8 meters multiplied by 5 meters equals 40 m^2.
Divide the volume in cubic meters by the area calculated in the prior step. With this example, let the volume be 200 cubic meters. Dividing 400 m^3 by 40 m^2 yields 10 meters, which is the prism's height.
Multiply each dimension by 1,000 to convert the meter measurements to centimeters. Concluding this example, 5 meters becomes 5,000 centimeters, 8 meters becomes 8,000 centimeters and 10 meters becomes 10,000 centimeters.
