The volume of the pyramid is 167.6 cube inch (approx).
Step-by-step explanation:
Given,
Each length (l) of the base of the pyramid = 8.3 in
Height(h) of the pyramid = 7.3 in
To find the volume of the pyramid.
Formula
Volume of the pyramid = 
×area of the base×height
Area of the base = l²
Now,
The volume of the pyramid = ×l²×h
= ×8.3²×7.3 cube inch = 167.6 cube inch (approx)
