No need to use the word grounded as past participle of grind. Just ground is enough.
Out of three rectangular faces we need only two faces. The third face is not needed.
More over as we observe the emerging light there would be two sets of waves coming from the two transparent faces. This would certainly disturb the experimental determination. Hence we have to grind any one of the three.

What are the plat surfaces on a pyramid cube or rectangular prism called?
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
