The volume of the pyramid is

Step-by-step 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

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,
,
and

Substituting these values in the formula
, we have,

Multiplying the numerator, we get,

Dividing, we get,

Thus, the volume of the pyramid is
