A piece of popcorn, on average, has a volume of 1.125 inches cubed. How many pieces of popcorn will fit in a bag that has a dimension of 5 inches by 3 inches by 7 inches?
To solve for this, we need to multiply all of our dimensions by each other, and then divide that product by the volume of a piece of the average popcorn. 5 x 3 = 15; 15 x 7 = 105.
105 / 1.125 = 93.33~.
This means that 93 (whole) pieces of popcorn will fit in a bag of 105 inches.
