Answer:
3870 boxes
Step-by-step explanation:
First you need to find the area of the box and the container
convert anything that needs converting so M to CM
then once you have done that divide the area of the container by the area of the boxes to get an answer
12 * 8 * 9 = 864cm^2
2.1 M * 100 = 210 CM
1.6 * 100 = 160CM
1 * 100 = 100 CM
210 * 160 * 100 = 3360000cm^2
336000 / 864 = 3870 boxes
