To find the number of cupcake boxes that fit in the larger box, we need to find the volume of the larger box and divide it by the volume of one cupcake box.
The volume of the larger box is 10.5 x 7 x 7 = 572.5 cubic inches.
The volume of one cupcake box is 3.5 x 3.5 x 3.5 = 42.375 cubic inches.
Dividing the volume of the larger box by the volume of one cupcake box, we get 572.5 / 42.375 = 13.5.
So, 13.5 cupcake boxes will fit in the larger box.
