Suppose you need 7.0m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car. How would you calculate the mass of this much chain? Set the math up. But don't do any of it. Just leave your answer as a math expression.

M = l × m

Explanation:

M = total mass

l = total length

m = mass per unit length

Note: The unit of weight in the question i.e. /kgm is wrong. The correct unit is kg/m.
