Okay, so I'm sure this has been asked a million times, and I should continue looking/searching old posts, but I've searched calculating, 2" blocks and lap quilt math and looked at least 15-20 posts per search and found nothing.

So, can anyone tell me how to calculate the number of 2" squares I would need for a lap quilt? Let's say 40X60, just to put a number on it.

I used to be really good at algebra, but I haven't taken a math class in more than 10 years and it's definitely a use it or loose it subject.

Thanks in advance.
