Calculating Al Foil Thickness in mm

[mightyhealthy]

Homework Statement

A Sheet of aluminum(Al) foil has a total area of 1.000ft^2 and a mass of 3.636g.

What is the thickness of the foil in millimeters (density of Al=2.699g/cm^3)?

Homework Equations

d=m/v

The Attempt at a Solution

1.347=totally wrong... help please

1.347 is probably the right answer in some system of units

Also, what is the d in your "relevant equations"? Is it the d for density? Or is it the d that is sometimes used for small distances (such as, say, thickness?) And what is v? How do you calculate it from the given data?

Your "attempt" is not so much an attempt from which we can clearly locate some error, as some numerical guess, without units or any other relevant information.

You're welcome.
I take it this means you solved it?
