\n" ); document.write( "To start with, the problem is deficient in not stating that the base of the pyramid is a REGULAR hexagon.

\n" ); document.write( "Next, it is not clear what \"base... being 5 units\" means.

\n" ); document.write( "Finally, the problem is overprescribed when the \"base\", volume, and height of the pyramid are all given and are not consistent.

\n" ); document.write( "The only possible way to solve the problem is to ignore one of the given pieces of information. Since it is not clear what a \"base of 5\" means, I will ignore that.

\n" ); document.write( "So my GUESS as to the correct information in the problem is a pyramid with a regular hexagonal base, a height of 10, and a volume of 750. Then....

\n" ); document.write( "\"V+=+%281%2F3%29%28B%29%28h%29\"
\n" ); document.write( "\"750+=+%281%2F3%29%28B%29%2810%29\"
\n" ); document.write( "\"B=+225\"

\n" ); document.write( "ASSUMING the hexagonal base is regular, each of the equilateral triangles that comprise the base have area 225/6 = 37.5. In terms of the length a of the apothem, that area (one-half base, times height) is \"A=%28a%2Fsqrt%283%29%29%28a%29\". So

\n" ); document.write( "\"37.5=a%5E2%2Fsqrt%283%29\"
\n" ); document.write( "\"a%5E2=37.5%2Asqrt%283%29\"

\n" ); document.write( "In exact form, the length of the apothem (with all the assumptions that have been made) is

\n" ); document.write( "\"sqrt%2837.5%2Asqrt%283%29%29\"

\n" ); document.write( "That's 8.06 to 2 decimal places.

\n" ); document.write( "Again, however, note that the presentation of the problem is exceedingly poor....
