To find the volume of the cube, you must first find the length of a side.
\n" ); document.write( "1.) To find length of a side, you must take the given area, \"25cm%5E2\", and solve for the side:
\n" ); document.write( " Area of square face is \"A=s%5E2\"
\n" ); document.write( " so, \"25cm%5E2=s%5E2\"
\n" ); document.write( " take the square root of both sides, \"sqrt%2825%29=sqrt%28s%5E2%29\"
\n" ); document.write( " therefore,the side length is \"s=5cm\"
\n" ); document.write( "2.) Next, solve for volume of the cube:
\n" ); document.write( " \"V=s%5E3\"
\n" ); document.write( " substitute \"5cm\" for \"s\";
\n" ); document.write( " \"V=5%5E3\", or \"V=5%2A5%2A5\"
\n" ); document.write( " \"V=125cm%5E3\"\r
\n" ); document.write( "\n" ); document.write( "To find the total length of all edges of the cube:
\n" ); document.write( "1.) A cube has 12 edges, so if each edge length is 5cm, then we can write as \"5cm%2A12=length_total\";
\n" ); document.write( "Therefore, \"5cm%2A12=60cm\"
\n" ); document.write( "
\n" );
