problems with fittings between surfaces

[FabioFino]

Hi, guys. .I am new to this forum and to tell the truth I am just looking at rhino5 and vray for the first time.. .
I have a problem of fitting an extruded surface (in subtraction). ..this subtraction, however,
is not linear but is tapered of 10°.The problem is that at the time of collecting the edges on the bottom of the extrusion,
It leaves me the corners open. What kind of help is there? I attach the file for clarity. . .

thanks in advance

try to proceed otherwise: collect the subtract piece and then perform the subtraction. I have however tried and with connection radius 0.1 (on the whole boundary of the bottom, in only operation) manages quite well. small defects remain on the edges at 90°, repairable by hand with a lot of patience.

thank you 1000 young people... I solved as suggested by you. Thank you.
