If answer is wrong please tell me

Answer 2

Answer:

• 64 cubes formed by big cube.

Step-by-step explanation:

Given:

• Edge of big cube = 20 cm
• Edge of small cube formed by big cube = 5 cm

To Find:

• How many small cubes formed from big cube.

Now,

⇒ Volume of big cube = side³

⇒ Volume of big cube = 20³

⇒ Volume of big cube = 8000 cm³

⇒ Volume of small cube formed by big cube = side³

⇒ Volume of small cube formed by big cube = 5³

⇒ Volume of small cube formed by big cube = 125 cm³

Now, we will find no. of cubes formed,

⇒ No. of cubes formed = Volume of big cube/Volume of small cube formed by big cube

⇒ No. of cubes formed = 8000/125

⇒ No. of cubes formed = 64 cubes.

Hence, 64 cubes formed by big cube.
