Answer 1

Following is the answer

Answer 2

Given,
Edge of cube=10 cm
Diameter of base of hemisphere=7 cm
To find,
Volume of the wooden article
ATQ,
Volume=Vol (Cube)- Vol (hemisphere)
= a^3- 2/3(πr^3)
=(10)^3-2/3*22/7*(7/2)^3
=1000-44/21*343/8
=1000-11/3*49/2
=1000-539/6
=(6000-539)/6
=5461/6
=91.16 cm^3

Hope it helps you!
