The M72 LAW has a penetration of 28cm or 11".
This gives you an Efactor of about 1100 (1185).
AV 48 = 2.54cm (1") steel.
11" is 11x thicker or ~3.5 doublings.
Final AV = 48 * (2.5^3.5) or about 1185.

It is been so long since I have done algebra I can't even make use of this formula.
This character ^ is stumping me. Google gave me some possibles but come nowhere near the answer of 1185.
