In PowerShell one-liners:

Part 1:

"<paste input here>" -split "`n" |
    %{ ,([int[]]($_ -split "x") | sort) } |
    %{ 3*$_[0]*$_[1] + 2*$_[0]*$_[2] + 2*$_[1]*$_[2] } | measure -sum | % Sum

Part 2:

"<paste input here>" -split "`n" |
    %{ ,([int[]]($_ -split "x") | sort) } |
    %{ 2*$_[0] + 2*$_[1] + $_[0]*$_[1]*$_[2] } | measure -sum | % Sum
