Calculating the volume of a square tank or vertical cylinder is a about the limit of my Math skills. embarrassingly it's been 25 years since i used cos or square root.
Could someone offer some insight on how to translate this equation into C++?

In case someone is interested in understanding why.. i have an unusual shape domestic heating oil tank and wish to use an HC-SR4 to measure the quantity of oil.
Thanks to all involved in supporting arduino.
