\r
\n" ); document.write( "\n" ); document.write( "Since all of the edges of a cube are of equal length, there is no need to differentiate between the length, width and height. The volume of a cube is determined by multiplying the length of three edges of the cube. Let \"\"a\"\" define the length of an edge of the cube.\r
\n" ); document.write( "\n" ); document.write( "Then the volume formula is defined as:
\n" ); document.write( "\"V+=+a+%2Aa%2A+a\"
\n" ); document.write( "This formula is also written as \"V+=+a%5E3\"\r
\n" ); document.write( "\n" ); document.write( "so, if given \"a=3cm\", than \"V+=+%283cm%29%5E3\"=>\"V+=+27cm%5E3\"\r
\n" ); document.write( "\n" ); document.write( "and your answer is (d) \"27\"
\n" ); document.write( "
\n" );
