    Geometry problem help!

    Three large water pipes run through the building. Enigeneers plan to enclose these water pipes within a ceramic-coated triangular casing to prevent radiation. Each of the water pipes has an outside diameter of 60 cm. If the cross section of the casing is an equilateral triangle, what is the smallest length possible?

    Problem could be worded this simply:
    An equilateral triangle's inscribed circle has diameter of 60 cm;
    what are the triangle's side lenghts?

    Use google...

    Hello, shawnrabe!

    We need clarification . . .


    Three large water pipes run through the building.
    Enigeneers plan to enclose these water pipes within a ceramic-coated triangular casing.
    Each of the water pipes has an outside diameter of 60 cm.
    If the cross section of the casing is an equilateral triangle, what is the smallest length possible?

    Why three pipes?
    I'm guessing that they are "bundled" togehter.
    Then the bundle is enclosed in a triangular casing.


    . . \begin{array}{c}<br />
* \\ [-1mm]<br />
/\! \bigcirc\! \backslash \\ [-1mm]<br />
/\! \bigcirc\!\bigcirc\! \backslash \\ [-1mm]<br />
*\!-\!-\!-\!* \\[-1mm]<br />
\end{array}


    Is that it?
