The formula for calculating the volume of the truncated square vertebral body:

\(V= \frac {h}{6} [ab+(a+a')(b+b')+a'b']\)

The calculation formula of the truncated edge length:

\(a1= \frac {a'b-ab'}{b-b'} \)

In the formula:

a'、b'、a、b——Upper and lower sides；

h——Height；

a1——Truncated rib

Usage example

Input data:

Upper bottom a1:10
