Answer 2

Answer :-

• The Volume of cube whose edge is 15mm is 3375mm³
• The volume of cube whose edge is 12.5 cm is 1953.125cm³

Step-by-step explanation :

To Find :-

• The Volume of cube

Solution :-

According the question, the edge of cube is,

As we know that,

Volume of cube = a³ cubic units,

• 15 mm

=> a³

=> ( 15 )³ cm³

=> ( 15 × 15 × 15 ) mm³

=> ( 225 × 15 ) mm³

=> 3375 mm³

Therefore, the Volume of cube whose edge is 15mm is 3375mm³.

• 12.5 cm

=> a³

=> ( 12.5 )³ cm³

=> ( 12.5 × 12.5 × 12.5 ) cm³

=> ( 156.25 × 12.5 ) cm³

=> 1953.125 cm³

Therefore, the volume of cube whose edge is 12.5 cm is 1953.125cm³.
