Question

A cube of 12 mm is painted on all its side . if it is made up of small cubes of size 3mm. if the big cube is splitted into those small cubes, the number of cubes that remain

Answer 1

VOLUME OF BIGGER CUBE = 12mm × 12mm × 12mm = 1728 mm³

VOLUME OF SMALLER CUBE = 3mm × 3mm × 3mm = 81mm³

TOTAL NO OF SMALLER CUBES = 1728/27 = 64

THUS THERE ARE 64 SMALLER CUBES OF 3mm SIDE

Answer 2

Answer:

There are $64$ smaller cubes.

Step-by-step explanation:

The dimension of bigger cube is $12mm$.

Dimension of smaller cube is $3mm$.

Volume of bigger cube $=12*12*12$

$=1728mm^{3}$

Volume of smaller cube $=3*3*3$

$=27mm^{3}$

Hence, number of smaller cubes $=1728/27$

$=64$

So, there are smaller $64$ cubes.
