Given:
The square base pyramid with height 3 cm and base edge 2 cm.
To find:
The volume of the square pyramid.
Solution:
Volume of a square base pyramid is:
...(i)
Where, B is the base area and h is the height of the pyramid.
Base is a square with edge 2 cm, so the base area is:

Where, a is the edge of the square base.


Putting
in (i), we get
Therefore, the volume of the given pyramid is 4 cm³.
It will be 1.52 or 1.5206349206
