How can I add SKU and product weight to my custom product tab?

Hi

I need some help, please. I am using expanses theme and have created a custom tab called “Specifications” where i added product dimensions (width, height and length) via the metafileds and added dynamically within that tab.

Now the problem I am facing is I need to add product SKU and Product weight which is part of Shopify product datafield. How can i add those within that tab, please?

I could not find much information about this on the internet.

Kindly help

Thanks
