Question

A rectangular shoe box measuring 18cm by 8cm by 12cm is filled with 3-cm cubes. What is the most number of cubes that can be fitted into the shoe box?

​

Answer 1

64 cubes

Explanation:

18/3 = 6

8/3 = 2.6...

12/4 = 4

6*2.6666666666*4= 64 cubes

Answer 2

64

Explanation:

18 x 8 x 12 = 1728 cm^3

Volume of each cube is 27 cm^3

So how many 27 cm^3 can we fit (or subtract) from 1728?

Divide! 1728/27 = 64 cubes

Correct me if im wrong, hope this helps
