Question

Write a program using switch case to find the volume of a cube a sphere and a cuboid. For an incorrect choice an appropriate error message should be displayed. a. Volume of the cube =s*s*s b.Volume of the sphere=4/3*3.14*r*r*r c. Volume of the cuboid=l*b*h

Answer 1

cuboids, cylinder, cone, sphere and hemi-sphere
