Actually, the pattern never uses a full 10" square - the biggest required is 8 7/8" for the large HST's, so linear quarter yards would work as well.
I would either buy an all-boy layer cake, or use yardage. I haven't checked Bree123's calculations, but they seem correct for yardage to replace the layer cakes.
