this is the middle part

anonymous · Answer

ohhh okay thanks now I get it

do you know how to do these??

hoblos · Answer

for these you must first calculate the volume of the full shape, assuming that it is not hollowed, then you calculate the volume of the hole and subtract it from the first volume
