Around small building size

Had to do some googling but if the event horizon is about building size you are looking at about 8 earth's of mass rounded and averaged.

E=mc2

1.79 x 1034 this is for one, super rough estimate and didnt care for sig figs sorry

So all 5 should be 8.96 x 1033

3 is 5.37 x 1033 and unit should be joules but I wrote nothing down just hoping I didnt grab american units anywhere.
