Three cubes of metal whose edges are 6 cm, 8 cm and 10 cm are melted and a new cube is made (i) Find the length of the edge of the new cube.
(ii) Find the total surface area of the new cube.
Let the radius and height of a cone be 24 cm and 6 cm respectively, then
r = 6 cm, h = 24 cm
Let radius of the sphere be r1 cm,
Since, the volume of clay in the form of a cone and the sphere remains the same. Therefore
