Use a 2-meter-long piece of wood and saw it into four legs of the same length. How high is this stool?

Two meters to five 3 mm saws equals 200- 1.5, which is 49.625. The clear height of tenon-grooved feet is 49.62, and the clear height of splayed feet is 4 cm. What don't you understand? I'm from a furniture factory.
