product volume calculation and summing

I am a new Opencart user and not very technical. I have a requirement that as each product is placed in the cart its volume is calculated. The volumes of all the products in the cart are totalled on checkout and the result is used to allocate a box(boxes) from a preselected range and shipping rates applied accordingly. Is there an extension for this or will it require new coding?

You can enter length, width, and height values for the products, and my Volume-Based Shipping extension can provide shipping rates based on the volume of the cart. Your rates need to be formula rates, though, not live rates like UPS or Fedex.

If you need other restrictions such as quantity, weight, total, or postcode, you can also use Formula-Based Shipping instead. Feel free to take a look at the screenshots and demo site (which includes some examples of various set-ups using the "Show Examples" button), and if you're interested let me know at www.getclearthinking.com/contact if you have any further questions.

Thanks for your quick reply I will take a look.

The is also a UPS and USPS extention that utilizes volume to estimate a shipping box to better estimate shipping costs for the live rates from UPS and USPS
