You can put this solution on YOUR website!
to solve this we must make 2 simple equations,\r
\n" ); document.write( "\n" ); document.write( "to calculate the volume of a cube you multiply the length width and height, however because they are all the same length it is X^3
\n" ); document.write( "the area of a cube is lxWx6sides, so X^2*6=100sqm.
\n" ); document.write( "first we must calculate the length of the side (x) by dividing 100/6 and square routing by 2.
\n" ); document.write( "so.
\n" ); document.write( "x^2=100/6
\n" ); document.write( "x^2=16.6666
\n" ); document.write( "x=16.6666^(1/2)
\n" ); document.write( "x=4.082482904m
\n" ); document.write( "do not round this number as we must use its value to calculate the volume of the cube.
\n" ); document.write( "the volume is 4.082482904^3
\n" ); document.write( "the volume of the cube is 68.0413....m cubed
\n" ); document.write( "so the volume is 68m cubed.\r
\n" ); document.write( "\n" ); document.write( "you do the same process for a sphere, the area equation is 4pi r^2 and the volume is (4/3)pi r^3\r
\n" ); document.write( "\n" ); document.write( "we are trying to isolate r\r
\n" ); document.write( "\n" ); document.write( "so 100=4(3.14...)r^2
\n" ); document.write( "100/4=3.14...r^2
\n" ); document.write( "25/3.14...=r^2
\n" ); document.write( "7.957747155=r^2
\n" ); document.write( "7.957747155^(1/2)=r
\n" ); document.write( "r=2.820947918m.\r
\n" ); document.write( "\n" ); document.write( "now you can calculate the volume of the sphere,\r
\n" ); document.write( "\n" ); document.write( "(4/3)pi(2.820947918)^3
\n" ); document.write( "volume of the sphere is 94.03m cubed\r
\n" ); document.write( "\n" ); document.write( "so the sphere holds more volume than the square.
\n" ); document.write( "
\n" );
