Mass absorption coefficients calculation?

I've just finished a 9 hour lab to get the results necessary to calculate the mass absorption coefficients for gamma rays in lead and aluminium.

Basically, I had a radioactive source and a Geiger Muller tube, then a variety of lead and aluminium sheets/blocks to absorb the gamma rays and measure the radiation count rates for different sheet thicknesses.

Our briefing sheet said to only measure the thicknesses of the sheets, but upon looking online at other labscripts, we need lengths and widths aswell which I don't have.

Is there a way to get the results I need with what I have?
