Convert my Ecxel Spreadsheet (Cubic Yard Calculation) to a website widget for Wordpress.

Hi, Local business here looking for assistance with our website. I have a spreadsheet (attached) which includes a math formula. I'd like to convert this to a web widget or a standalone webpage on my website. The math is designed as a mulch calculator. ie how much it would cost to cover a playground with mulch. I'm unsure of the complexity of this conversions so any info would be of great help. I will ask for complete installation. You will be given access to word press where you will install as page/wiget Please see attached spreadsheet.
