Answer:
Number of cookie boxes will fit into the large box = 40
Step-by-step explanation:
Length breadth and height are given in order.
Size of large box = 10 in x 10 in x 12 in
Size of small box = 2 in x 5 in x 3 in
Complete volume of large box can be utilized since length breadth and height of large box is multiple of small box.
Volume of large box = 10 x 10 x 12 = 1200 in³
Volume of small box = 2 x 5 x 3 = 30 in³
Number of cookie boxes will fit into the large box

Number of cookie boxes will fit into the large box = 40
