Solution Verified by Toppr

Correct option is A)

Volume of hollow cube =(22)

3 Radius of marble = 2 0.5 ​ = 4 1 ​

Volume of each marble =4πr

3 = 3 4 ​ × 7 22 ​ × 4 1 ​ × 4 1 ​ × 4 1 ​ = 168 11 ​ cm 3

Space of cube occupied by marbles =V−

8 1 ​ V = 8 7V ​

∴  Number of marbles =

168 11 ​ 8 7V ​ ​ = 168 11 ​ 8 7 ​ ×22×22×22 ​ =142,296

Then the number of marbles that the cube can accomodate is

a. 142296 b. 142396 c. 142496 d. 142596

Solution:

It is given that

The internal edge of a hollow cube = 22 cm

Volume of cube = side³ = 22³ = 10648 cm³

Diameter of special marbles = 0.5 cm

Radius of special marbles = 0.5/2 = 1/4 cm

We know that

Volume of one marble = 4/3 πr³

Substituting the values

Volume of one marble = 4/3 × 22/7 × (1/4)³

= 11/168 cm³ Here

Filled space of the cube = Volume of cube - 1/8 volume of cube

= 10648 - 1/8 × 10648

= 10648 × 7/8 = 9317 cm³

So the required number of marbles = total space filled by the marble in one cube/ volume of one marble

= 9317/ (11/168) = 142296

Therefore, the number of marbles that the cube can accomodate is 142296.

Option (A) is correct.

Given , edge of the cube = 22 cm

∴ Volume of the cube = 22 3 = 10648 c m 3 [Volume of cube = s i d e 3 ]

Also, given diameter of marble = 0.5 cm

∴ Radius of a marble, ⇒ r = 0.5 2 = 0.25 c m [Diameter = 2 × r a d i u s ]

Volume of one marble

= 4 3 π r 3 = 4 3 × 22 7 × ( 0.25 ) 3 Volume of sphere = 4 3 × π ( r a d i u s ) 3 = 1.375 21 = 0.0655 c m 3

Filled space of cube = Volume of the cube - [

1 8 × Volume of cube ] = 10648 − ( 10648 × 1 8 \ = 10648 × 7 8 = 9317 c m 3 ∴

Required number of marbles

= T o t a l s p a c e f i l l e d b y m a r b l e s i n a c u b e V o l u m e o f o n e m a r b l e = 9317 0.0655 = 142244 ~ (approx.)

Hence, the number of marbles that cube can accommodate is 142244.
