The base is a right triangle with a hypotenuse measuring 5 inches and a leg measuring 3 inches.
\n" ); document.write( "According to Pythagoras theorem, the other leg must measure 4 inches, because
\n" ); document.write( "\"3%5E2%2B4%5E2=5%5E2\"
\n" ); document.write( "The triple 3,4,5 is the best known and most popular of the Pythagorean triples, those sets of 3 positive integers with the square of the largest equal to the sum of the squares of the other two.
\n" ); document.write( "So the base of that pyramid is a triangle with two perpendicular sides measuring 3 and 4 inches. Calling one of them the base of the triangle, and the other one the height of the triangle, the area of the triangle, In square inches, is calculated as
\n" ); document.write( "\"%281%2F2%29%2A3%2A4=6\"
\n" ); document.write( "The volume of a pyramid is 1/3 times the area of the base, times the height of the pyramid.
\n" ); document.write( "For the pyramid in the problem, the volume, in cubic inches, is
\n" ); document.write( "\"Volume=%281%2F3%29%2A6%2A8=16\"
\n" ); document.write( "
