The formula for finding the Volume of square pyramid is given by :
[tex] V = a^{2} \frac{h}{3} [/tex]
where a is base edge and,
h = height.
We are given in the figure,
base edge = 18cm
Height =12 cm
So plugging these values in the formula for volume , we have
[tex] V = (18)^{2} \frac{12}{3} [/tex]
On solving we get ,
Volume of square pyramid = 1296 cm³.
So first option is the correct choice .
