Given the MDX query below:

SELECT
Time.Fiscal.FiscalYear.[2002/03] :
Time.Fiscal.FiscalYear.[2007/08] ON ROWS,

Crossjoin({Region.London, Region.SouthEast, Region.RestOfUK},
{Sector.Retail, Sector.Office, Sector.Other}) ON COLUMNS

FROM
FinancialCube

WHERE
(Measures.Turnover,
Residential,
Actual)
What is the answer to the questions below, explaining any assumptions you’ve made:

a) What is the dimensionality of the ROWS axis?

b) What is the dimensionality of the COLUMNS axis?

c) How many rows and columns would you expect to find in the resulting cellset?

Thank you for your advice in advance.
