I believe that your asking for two answers. The volume of the pyramid is 15 cubic centimeters and If the slant increases by 4 centimeters and its hheight increases by 2 centimeters the volume increases by 6 centimeters because the answer would be 21. 21-15=6. Formula to get the volume of a pyramid is V=1/3*(L*W)*H. I could be wrong.
