What is the total volume of local anesthetic in two carpules?

Explanation:
Each dental cartridge contains 1.8 mL of local anesthetic. Using two carpules doubles that amount: 1.8 mL × 2 = 3.6 mL. So the total available volume from two carpules is 3.6 mL. This matters because the total volume, along with concentration, determines the total dose delivered. The other numbers would correspond to different per-carpule volumes, but with the standard cartridge size, two carpules yield 3.6 mL.
