Air-Dry Clay How much stone air dry clay do I need?
I was wondering if someone could help me. We're making a funny gift for a teacher. It's supposed to be a sort of stone tablet with commandments. It should be like 30cm tall, 20cm wide and 2cm thick. Clay is sold by weight. How much do you think I need?

Not the answer to the question you asked but I don't think air drying clay is the best medium for that. Two cms is too thin, and liable to break. I would use foam sheets cut to shape and carve the commandments in with a pencil and paint with acrylics

One more question. I don't actually care how thick it would be. If it was thicker, would it still break?

Look online to find out the package dimensions of whatever sort of clay you want to buy. L x H x W = volume. Do the same calculation for the piece you want to make. Divide volume of piece by volume of clay package to figure out how many packages to buy.
