You can put this solution on YOUR website!
given: sides of pyramid base are \"4cm\", volume is \"80cm%5E3\"\r
\n" ); document.write( "\n" ); document.write( "volume of a pyramid; \"v+=+%281%2F3%29%2Ah%2Aarea+of+base\"
\n" ); document.write( "area of the base; \"a+=+s%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for base area:
\n" ); document.write( "\"a+=+4%5E2\"
\n" ); document.write( "\"a+=+16\"\"cm%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for \"h\" using volume formula:
\n" ); document.write( "\"80+=+%281%2F3%29%2Ah%2A16\"
\n" ); document.write( "\"5+=+%281%2F3%29%2Ah\"
\n" ); document.write( "\"h+=+15\"\"cm\"
\n" ); document.write( "
