Question

the side of cube whose volume is 1 cubic centimetre is
​

Answer 1

Let V

1

​

,V

2

​

,V

3

​

are the volumes of the three cubes and a

1

​

,a

2

​

,a

3

​

are sides of the three cubes.

We know that,

⇒ a

3

=V

So,

⇒ a

​

=V

​

⇒ a

cm

Similarly,

⇒ a

​

=1 cm

And

⇒ a

​

=2 cm

So the height of the resulting structure =

=0.5+1+2

=3.5cm

Answer 2

Answer:

$Let \: side \: of \: cube \: be \: 'x' \: cm \\ </p><p>volume \: of \: cube = 1 {cm}^{3} \\ {x}^{3} = 1 \\ {x}^{3} = {1}^{3} \\ x = 1 \: cm$
