Pythagorean theorem:
a^2+b^2=c^2 (C^2 always is the hypotenuse)
21^2+b^2=29^2
441+b^2=841
841-441=400
square root of 400 is 20
Your answer is 20

8 ounces = 1cup
2 cups = 1 pint
So, 16 ounces = 2 cups = 1pint
16 ounces = 1 pint
If you have 8 ounces, you would have half a pint.
If you have 20 ounces:
20 ounces/16 ounces= 5/4
So, you'd have 1 1/4 or 1.25 pints
