During a Rockwell Hardness test, what dimension is measured?
- The diameter of the indent.
- The depth of the indent.
- The diameter and depth of the indent.
Explanation from PART66Online
The Rockwell test presses an indenter under a fixed load and reads hardness directly from the depth of penetration of the indent, with a deeper indent meaning a softer material. It differs from the Brinell and Vickers tests, which optically measure the diameter or diagonal of the impression rather than its depth.

isn't what we should see in the microscope is the diameter of the indent and then calculate the area, then knowing the depth?

No, you miss matched it with the Brinell Tester. With the brinell tester you have to measure and calculate it.
