How many cubic feet of sand will I need to fill a pipe 1.5\" I.D. which is 10 feet long?
\n" ); document.write( ":
\n" ); document.write( "Use the volume of a cylinder: V = \"pi%2Ar%5E2%2Ah\"
\n" ); document.write( "Diameter of 1.5, a radius of .75 inches
\n" ); document.write( "Change length to inches also; 12(10) = 120 inches
\n" ); document.write( "V = \"pi%2A.75%5E2%2A120\"
\n" ); document.write( "V ~ 212 cu/in
\n" ); document.write( ":
\n" ); document.write( "Change to cubic ft, there are 1728 cu/in in 1 cu/ft
\n" ); document.write( "\"212%2F1728\" = .123; roughly \"1%2F8\" cu/ft
\n" ); document.write( "
