How is the CPU utilization is being calculated here? When I have only 46 pods and each one of them not crossing max 10m cpu?

metrics-server pulls from the embedded cadvisor in each Kubelet. It polls every 60 seconds by default and the CPU usage is looking a total CPU usage seconds over the last few time periods as a fraction of wall clock elapsed time.
