Question

a cubical solid block of metal 49 cm * 44 cm * 18 cm is melted and formed into solid sphere calculate the radius of the sphere

Answer 1

rectangle length = 49cm

rectangle breath =  44cm

rectangle height = 18cm

volume of rectangle be V  = length x breath x height

volume = V = 49 x 44 x 18

V =  38808 cm3

now all the rectangular block is converted into sphere so volume of sphere is same as of rectangle

volume of sphere = 4/3πr^3

 38808 = 4/3 x 22/7 x r3

38808 = 88 / 21 x r3

38808 x 21 / 88 = r3

9261 = r3

r = 21 cm,

HOPE IT HELPSSSSS....

Answer 2

cubical solid height=49cm
cubical solid breath=44cm
cubical solid height=18cm
