Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

[tex]V = \frac{a^2h}{3}[/tex]

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

[tex]V = \frac{18^2\times 12}{3}[/tex]

[tex]= \frac{324\times 12}{3}[/tex]

[tex]=\frac{3888}{3}[/tex]

[tex]=1296[/tex] cube cm.

First option is correct.
