Answer 1

Length times weight times height should give you the answer

Answer 2

Well we know that 
105° +z should equal 180° 
So 105° +z=180° 
z=180° -105° 
z=75° 
Now we only need the y
All of the inside angles together should equal 360° 
102° +83° +75° +y=360° 
260° +y=360° 
y=360° -260° 
y=100°
