My customer wants white stone rocks in the front of his house. He changed his mind from Mulch to either Vista red rocks or white. I couldn't find an online tool for a calculator. I will be honest im new to knowing how many bags I need. First bed on the left: 56" X 210" Second bed: 223" 60" I know its a small lawn, lol. But the problem is that there's a crazy wavy design so I of course chose the longest measurement which was 60'' long from the foundation. Thanks guys for the help.
