The height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of an oblique triangular pyramid is given by:

Where b is the area of the base and h is the height of the pyramid.
We have b = 21 square units and V = 126 cubic units.

h = 18 units
Thus, the height of the oblique triangular pyramid is 18 units if the base area of 21 square units and a volume of 126 cubic units.
