What is the volume of this square pyramid?
tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

V = \frac{a^2h}{3}

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,

V = \frac{18^2\times 12}{3}

= \frac{324\times 12}{3}

=\frac{3888}{3}

=1296 cube cm.

⇒ First option is correct.
