### Volume of a Triangular Tank

Subject: Volume of a Triangular Tank

Dear Doc:

I am trying to find the volume of a triangular tank that measures
3'4" X 3'4" X 5' and measures 22" in height. I know how to find the
area of the triangle by applying "Heron's" formula, but the volume is
giving me some problems.

Thank you,

DWD

The area of the triangle is easy to calculate either by Heron's
formula, or since this is an isosceles triangle by (1/2)*product of
two sides*sine of angle between those sides.  I get 5.512 ft^2.

Simply multiply by the height (in feet) to get volume = 10.105 ft^3
