Sorry the book on my desk doesn't have asbestos sheeting mass.
But a quick search turned up this:-
http://www.p1m.com/m-w.htm
It has corrugated asbestos cement roofing a 4lb/sq.ft.
1 ft = 305mm , 1lb = 0.45kg , 1 tonne = 1000kg
(edit to change to pounds, my bad)

Not enough information is given. What is the density of the matieral? How thick are the sheets?

you need another dimension of length. I will call it x in this case. The density is p:
m = pV = 3.6xp (kg if x and p are in SI)
If you can pay by square metre you need 3.6m^2
