Question

A cone of maximum size is curved out from a cube of edge 14cm. Find the surface area of remaining solid after the cone is curved out​

Answer 1

Answer:

vol. of remaining part =

vol.of cube -vol.of cone

ie.,

a3 - 1/3 *22/7 *r^2 * h

a=14 cm

:a^3 = 14 *14 *14

=2744

:2744 -1/3*22/7 * 7 *7 * 14

:2744-1/3 *22 *7*14

:2744 - 2156/3

:2565. 34
