The base of a pyramid is a right triangle.
What is the volume of the pyramid?

792km^3

Step-by-step explanation:

The volume of pyramid is calculated by multiplying l×w×h and that's divided by 3 (l: length, w: width, h: height)

Height of this pyramid : 22km

Width of this pyramid : 9km

Length of this pyramid : 12km we have to multiply these values and divide the result by 3

22×9×12 ÷ 3 = 792km^3

Volume of the pyramid=

Step-by-step explanation:

Volume of a right triangular pyramid =

Where A= Area of the base triangle of the pyramid

  and   H = Height of the Pyramid from base to top of it.

In the base triangle:

Length of base= 12 Km           Length of Altitude of base triangle=9 km

Area of the base triangle(A)

Volume of the pyramid=                                         :

       Volume of the pyramid=
