Question

The volume of a cube of side 2a is ?
​

Answer 1

Answer:

• Volume of cube is 8a³.

Step-by-step explanation:

According to the Question

It is given that ,

• Side of cube ,s = 2a

we have to calculate the volume of cube

As we know that ,

volume of cube is calculated by

• Volume of Cube = Side³

by putting the value we get

→ Volume of Cube = 2a × 2a × 2a

→ Volume of Cube = 8a³

• Hence, the volume of cube is 8a³ .

Answer 2

Answer:

Thanks for your question...

Your required answer :

• Volume of cube = a³
• Given side = 2a

Therefore volume of cube :

= (2a)³

= 8a³

So, 8a³ is the correct answer..
