You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new Excel workbook, and create a query based on the Tallest buildings worksheet in the Tables workbook in the above folder.
Apply transforms and create a new Metres per floor column to get this:
Use the pinnacle height to get the height in metres and feet, and remove the roof height column.
Warning: the character before the m and ft at the end of the height in metres and feet doesn't seem to be a space. Your best bet is to remove the m and ft, and then apply the Trim transform (if you can find it, that is).
Now get rid of all but these 3 columns:
You'll also need to remove any buildings with null completion years, and sort by the completion year.
Create a pivot transform to show the number of buildings by country and completion year:
The first few countries and years that you should see.
Show this data in a PowerPivot data model.
Save your workbook as But why, and close it down.
