	why do the brinell hardness numbers obtained from the depth of indentation usually differ from those computed from the diameter of indentation?

You are performing the test improperly.

Brinell Hardness Test Method
The Brinell hardness number is a function of the test force divided by the curved surface area of the indent. The indentation is considered to be spherical with a radius equal to half the diameter of the ball. The average of the two diagonals is used in the following formula to calculate the Brinell hardness.
