Volume of a triangular pyramids is given by:
......[1]
where
V is the volume of the triangular pyramid
B is the base area
h is the height of the pyramids
From the given figure:
h = 32 cm
to find the Area of the base.
Use formula:
where x represents the width and y represents the height of the Base in the pyramids.
Here, x = 9 cm and y = 15 cm
then;
centimeter square.
Substitute the value of B in [1] we get;
Simplify:
V = 720 centimeter cube
Therefore, the volume of the given pyramids is 720
