Multiplying Weight of product by Quantity

Multiplying Weight of product by Quantity

I am facing an issue with creating a report that consolidates the total sales volume in kilograms.

  1. I have already specified the weight for each product.
  2. I have also aggregated the total sales quantity.

The key question is: how can I create a report that multiplies the weight by the quantity for each item, as shown in the attached image?

Let me know if you need further.
