Finding cubic meters is the same thing as finding the volume of an item, measured in meters. Take a few measurements, do a simple calculation, and you have your answer. Just grab your metric ruler and use the formula H(eight) x L(ength) x W(idth) to determine the cubic meters of any item.
One cubic meter is the same as 1,000 liters, 35.3 cubic feet and 1.3 cubic yards.
Watch the video below for an example:
Tip: Convert measurements to meters if they are not already. If measurement was taken in millimeters, divide by 1,000. If by centimeters, divide by 100. If all you have is a standard ruler, convert feet to meters by multiplying the measurement in feet by 0.3048.
