Question

how many solid coins of diameter 6cm and thickness 0.2 cm can be made by melting a solid metal cuboid of length 33cm breath 18cm and height 8cm ? then give answer with solution


The total length of all the edges of a cube is the difference in the number denoting its total surface area
and volume ?


what is the total surface area of a cylinder whose radius is 14cm and height 15cm?

what is the slant height of cone whose radius is 14cm and the curved surface area 2200cm square​

Answer 1

Answer:

Here is ur answer dear.....❤❤❤❤

volume of cubiod =lbh

=33×18×8 cm cube

= 4752 cm cube

now cions are made by melting the solid metal cubiod therefore there volume must be equal

Therefore.

volume of circular cions = pie ×r×r×h

= 22/7 ×3×3×0.2 r=d/2 =6/2 =3 and thickness = 0.2

=39.6/7

=396/7×10

no of cions =volume of cubiod/volume of cions

=4752×7×10

-----------------

396

=332640

------------

396

=840 cions
