The cube

The cube has an edge of 25 cm. We cut it into small cubes of 5 cm long side. How many of these little ones left when we build a new cube of 20 cm in length?

Correct answer:

n =  61

Step-by-step explanation:

a=25 cm b=5 cm c=20 cm  V=a3c3=253203=7625 cm3 V1=b3=53=125 cm3  n=V/V1=7625/125=61
