Answer 2

To solve : Find the sum of cubes of $6$  and $60$ and subtract it from the sum of cubes of $7$  and $70$ .

Solution :

• As per the given data we have to find  sum of cubes of $6$  and $60$ and subtract it from the sum of cubes of $7$  and $70$ .
• Cube of number is to multiply the given number by itself three times .  
• Cube of $6 = 6\times 6\times 6$

                         $= 216$

• Cube of $60 = 60\times 60\times 60$

                          $= 216000$

• Sum of $6$  and $60$

       $216 + 216000 = 216216$  --------------(i)

• Cube of $7 = 343$
• Cube of $70 = 343000$
• Sum $7$  and $70$ .  =  $343 + 343000 = 343343$  ------------(ii)
• Subtracting (i) from (ii) :
• $343343-216216 =127127$

Hence , required difference is $127127$ .
