Question

A paper is rectangular in shape with negligible thickness. A stack of papers is arranged one above the other.

S1 : The resulting figure is three dimensional.

S2 : The figure is called a cuboid.

• A. S1 is true but S2 is false
• B. S1 is false but S2 is true
• C. S1 and S2 are true
• D. S1 and S2 are false

Answer 1

The correct option is C

S1 and S2 are true

A single sheet of paper is 2 dimensional having only length and breadth since thickness is negligible.

​

Stacking of papers results in a figure having length , breadth and height(thickness) thus having 3 dimensions.

Therefore, S1 is true. The resulting figure is called a cuboid. Thus, S2 is also true. Hence, both S1 and S2 are true.
