document.write( "The volume V of a pyramid varies jointly as its altitude H and the area of its base. A pyramid with a nine-inch square base (a square base 9 inches on each side) and an altitude of 10 inches has a volume equal to 270 in^3. Find the volume of a pyramid with an altitude of 6 inches and a square base 4 inches on each side. (units optional) \n" );

Algebra.Com's Answer #29106 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! The joint relationship can be expressed as \n" ); document.write( "V = kbh (here b = s^2) \n" ); document.write( "now plug in what we know to find k... \n" ); document.write( "270 = k(81)(10) so that \n" ); document.write( "k = 1/3 \n" ); document.write( "Now rewrite using the new k and the data to find the new volume... \n" ); document.write( "V = (1/3)bh \n" ); document.write( "V = (1/3)(16)(6) \n" ); document.write( "V = 32 in^3 \n" ); document.write( " |
