Answer / hareshvaity

cyclometric complexity is used to calculate the path
coverage, which is one of the white box testing method.

There is no such formula to calculate the no. of test cases
required. It will depend on the Functionality to be tested
and the testing method.
e.g while using black box testing, boundry value analysis,
equivalence partitioning can be used to write test cases. In
white box testing, statement/decision/condition/path
coverage can be used.
