<h3><u>Answer:</u></h3><em><u>The formula represents the volume of the pyramid is:</u></em>
<em><u>The volume of square pyramid is given by formula:</u></em>
Where, "h" is the height of pyramid
"a" is the length of side of base
Here given that, pyramid has a square base with sides of length s
Therefore,
a = s
The height of the pyramid is equal to 1/2 of the length of a side on the base
<em><u>Thus the volume of pyramid becomes:</u></em>
Thus the formula represents the volume of the pyramid is
