Maths for the PSU power requirement

Hello,

 

I understood 90% of the document below, about Juniper MX480 power requirement. but I do not undertand 2 things :

 

in section 2 : evaluate the power budget  for AC chassis

how is the value 1360 W is calculated ? what does this value mean

 

in section 3 : calculate input power

 

how are the value  1282W and 1090 W calculated

 

The details will help me understand. thanks
