V = 120 in^3

Here is why:

The volume formula for a pyramid is:


V=(1)/(3)Bh

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:


A=(1)/(2)bh

Plug in the numbers.


A=(1)/(2)*9*10

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.


V=(1)/(3)*45*8

V = 120 in^3
