Question

A cubical block of wood whose side is 600 cm is cut into cuboidal pieces of dimension 30 cm X 20 cm X 15 cm. Find number of cuboidal pieces cut from the cubical block *

Answer 1

Answer:

Time period of SHM of small vertical oscillations in a liquid is given by T=2π

g

l

, where l is the length of cube/cylinder dipped in the water.

So according to law of floatation,

weight of the cube = weight of the water displaced

abc×d×g=bcl× 1×g

⇒l=da

⇒T=2π

g

da

Answer 2

Answer:

volume of cubical block = 600³ = 216,000,000

volume of 1 cuboidal block= 30 × 20 × 15 = 9000

now,

no. of cuboidal pieces = 216,000,000/ 9000

= 24000 blocks..
