P(even number) = 8/16 = 1/2...sample space is 16, there are 8 even numbers (2,4,6,8,10,12,14,16)
P (odd prime number) = 5/16...sample space is 16, there are 5 odd primes (3,5,7,11,13)
P (both) = 1/2 + 5/16 = 8/16 + 5/16 = 13/16 = 0.8125 rounds to 0.813

Solve for the Volume of each box by multiplying the dimensions together.
Box 1: 10*10*10 = 1000
Box 2: 20*5*10 = 1000
Box 3: 8*8*10 = 640
Box 4: 10*20*6 = 1200
Since 640 is less than 924, Box 3 is too small
The complementary angle of 12 degrees, is 78 degrees.
Complementary angles are angles that when added together have an end result of 90 degrees. So, to find the answer, simply subtract 12 from 90. Thus making the answer 78 degrees.
I hope this helps!
