Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep. She wants to fill the box with other packages that are 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
What is the greatest number of packages that she can put in the box without it overflowing?

50 packages

Step-by-step explanation:

Area of the box: A= (l)(w)(h)

                              =(20)(5)(10)

                              =1000cm^3

Area of the package: A= (5)(1)(4)

                                      =20cm^3

1000/20=50 packages

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
