<h3>What is Volume?</h3>
Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. Volume is measured in cubic units like m³, cm³, in³, etc. Volume is sometimes referred to as capacity.
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
Given:
base = 20 inches
height = 30 inches
Now, volume of pyramid
Volume = a²h/3
Volume = 20 x 20 x 30 /3
Volume = 400 x 10
Volume = 4000 inch³
Hence, the volume of pyramid is 4000 inch³.
