contemporary extrusion of multiple faces of a solid

[joe]

Good morning to all
the problem is to speed up the operation of extrusion of faces belonging to a series of solids: Is there a way to extrude faces at once?

thanks I solved with the command presses and drags
but with the command extrudes solid editing faces, it does not work
