Steps:

(a) A brick

Vertical cut. We will get

2

rectangle shape pieces of length half the length of brick but breath will be same

Horizontal cut. We will get

2

pieces of rectangle shape each of same length but with half the breath of the brick.

(b) A round apple

Vertical cut. We will get

2

semi-circle shape pieces of same diameter.

Horizontal cut. We will get

2

semi-circle shape pieces of same diameter.

(c) A dice

Vertical cut. We will get

2

rectangular shape pieces of length half the side of dice but breath will be same as side of dice.

Horizontal cut. We will get

2

pieces of rectangular shape each of length equals to side of dice but breadth will be half of side of dice.

(d) A circular pipe

Vertical cut. We will get

2

rectangular shape pieces. Length will be equal to height of circular pipe and breadth will be equal to diameter of circular pipe

Horizontal cut. We will get

2

pieces of circular pipe but their height will be half of original circular pipe

(e) An ice cream cone

Vertical cut. We will get

2

triangular shape pieces

Horizontal cut. We will get

1

piece of small cone shape and

1

frustum shape piece.
