_________km3 what is the volume of the pyramid
harkovskaia [24]

The volume of the pyramid is 792\ km^3

Explanation:

It is given that the base of the pyramid is a right triangle.

The formula to determine the volume of the pyramid is given by

V=\frac{l w h}{3}

where l is the base length of the pyramid,

w is the base width of the pyramid and

h is the height of the pyramid.

From the figure, we can see that,

l=9, w=12 and h=22

Substituting these values in the formula V=\frac{l w h}{3} , we have,

V=\frac{(9)(12)(22)}{3}

Multiplying the numerator, we get,

V=\frac{2376}{3}

Dividing, we get,

V=792

Thus, the volume of the pyramid is 792\ km^3
