Volume of the pyramid = 396
$\text{km}^3$

Solution:

Base of the triangle (b) = 9 km

Height of the triangle (h) = 12 km

Base area of the triangle (B) =
(1)/(2) bh

$=(1)/(2)*9*12

Base area of the triangle (B) = 54 km²

Height of the pyramid (H) = 22 km

Volume of the pyramid =
(1)/(3)BH

$=(1)/(3)*54*22

= 396
$\text{km}^3$

Volume of the pyramid = 396
$\text{km}^3$

Hence the volume of the pyramid is 396
$\text{km}^3$ .
