Question

A cone shaped hole is drilled into a cube that has a side legnths of 20cm. Find the remaining volume

Answer 1

volume of a cube=a^3

now volume= 20^3=8000

volume of a cone=1/3π(r^2)h

now volume of the cone=1/3 *22/7*10*10*20

remaining volume= volume of cube-volume of cone

8000-44000/21=(168000-44000)/21=124000/21
