Sony RX10 III cropping / digital zoom question

I am wondering about the Sony RX-10 III (1 inch sensor with 20 mp, 24-600 mm equiv 35mm).

If I crop an image until half of the sensor area - would the zoom reach then be double = 1200 mm? What about the pixels, does it go down 50% to 10mp then? And cropping down to 1/3 of the sensor, is it then 1800 mm reach and 6.7 mp?

Instead of cropping in PS, digital zoom is an alternative of course, but I am not sure about the digital zoom capacity of this camera, is it up to 4X?
