if the figures are similar then their sides are proportional.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a side of the yellow eraser is equal to 16.
\n" ); document.write( "the corresponding side of the white eraser is 2.
\n" ); document.write( "the ratio of the sides is y/w = 8/1.
\n" ); document.write( "this means that the yellow eraser is larger than the white eraser by a factor of 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the object are similar with a ratio of 8:1, then their areas are proportional with a ratio of (8/1)^2 and their volumes are proportional with a ratio of (8/1)^3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this means the surface area of the yellow eraser is 64 times the surface area of the white eraser.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this means that the surface area of the white eraser has to be equal to .8125 because .8125 * 64 = 52.\r
