How many m and ms fit in a 36 oz jar?

To estimate how many M&M's fit in a 36 oz jar, we first need to know the approximate volume of a single M&M, which is about 0.5 cubic centimeters (cc). Since there are about 29.57 cc in an ounce, a 36 oz jar has approximately 1,066 cc of volume. Dividing the jar's volume by the volume of an M&M suggests that roughly 2,132 M&M's could fit in the jar, considering some space is lost due to packing inefficiencies.
