No not rational because you cant divide it
In the given graph, lets mark two points:
Let
and 
The slope of the line is given by:



The equation of the line is given by:






Therefore, the function equation represented by the graph is: 
Formula:
V = 1/3 * b^2 * h
Plug in what we know:
V = 1/3 * 7^2 * 16
Simplify the exponent:
V = 1/3 * 49 * 16
Multiply all 3 numbers together:
V = 261.3cm^3
