**Question 1**:

The diagram above
shows a solid consisting of a right prism and a half-cylinder which are joined
at the plane

*EFGH*.*EF*is the diameter of the semi-circle and is equal to 3cm. The base*ABCD*is on a horizontal plane and*AB*= 6cm,*BC*= 4cm. The vertical plane*ABFE*is the uniform cross-section of the prism.
Draw to full scale, the plan of the solid.

*Solution:***Question 2**:

Diagram above shows a
solid right prism with rectangular base

*ABCD*on a horizontal table. The vertical plane*ABEHIL*is the uniform cross-section of the prism. Rectangle*LIJK*,*IHGJ*and*HEFG*are inclined planes.*AL*,*DK*,*BE*and*CF*are vertical edges.
Given

*BC*= 4cm,*AB*= 6cm.*EB*=*FC*=*LA*=*KD*= 4cm, The vertical height of*I*and*J*from the rectangular base*ABCD*= 3cm, while the vertical height of*H*and*G*from the rectangular base*ABCD*= 5cm.
Draw
to full scale, the elevation of the solid on a vertical plane parallel to

*BC*as viewed from X.

*Solution:*
