3. Find the volume of the pyramid.

Gnoma [55]

Answer:

$916.11\:ft^{3}$

Step-by-step explanation:

Volume of the hexagonal pyramid = $1/3\times (area\: of \: hexagonal\:base)\times height$

Here sides of hexagonal base = 9 ft

So, Area of hexagon = $6\times \frac{\sqrt{3} }{4} a^{2}$

$6\times \frac{\sqrt{3} }{4} \times 9 \times 9$

$= 210.5$

Height is given, 13 ft

So, volume = $1/3\times 210.5\times 13$

$= 916.11\: ft^{3}$
