Find the volume and total area of the largest cube of wood that can be cut from a log of circular cross section whose radius is 12.7 in. (use ft. as unit)
\n" ); document.write( ":
\n" ); document.write( "The cube's square side's hypotenuse will be the diameter of the log: 25.4\"
\n" ); document.write( "Let x = the length of one side
\n" ); document.write( "x^2 + x^2 = 25.4^2
\n" ); document.write( "2x^2 = 645.16
\n" ); document.write( "divide both sides by 2
\n" ); document.write( "x^2 = 322.58; the area of one side
\n" ); document.write( "x = \"sqrt%28322.58%29\"
\n" ); document.write( "x = 17.096 in, one side of the cube
\n" ); document.write( "Find the vol of the cube
\n" ); document.write( "Vol: 17.096^3 = 5793.7 cu/in
\n" ); document.write( "Change to cubic ft (1728 cu/in in one cu ft)
\n" ); document.write( "\"5793.7%2F1728\" = 3.353 cu/ft
\n" ); document.write( ":
\n" ); document.write( "Find the total surface area: 6(322.58) = 1935.48 sq/in
\n" ); document.write( "Change to sq/ft; (1 sq/ft = 144 sq/in)
\n" ); document.write( "\"1935.48%2F144\" = 13.44 sq/ft
\n" ); document.write( "
\n" ); document.write( "
