A 200 cm long, 100 cm wide and 1 cm thick steel plate, after forging, has the same width and 60% increase in length. What is the thickness of the steel plate after forging?

A 200 cm long, 100 cm wide and 1 cm thick steel plate, after forging, has the same width and 60% increase in length. What is the thickness of the steel plate after forging?

Volume: 200 * 100 * 1 = 20000 (cm3)
Current thickness: 20000 / [200 * (1 + 60%) * 100] = 0.625 (CM)
That is, the thickness after forging is 0.625cm
