(7 3/4 mi/h)*(2 2/3 h) = 20 2/3

A calculator that works with mixed numbers is a handy thing.
Answer:
628.3 mi ³
Step-by-step explanation:
The formula for the volume of a cylinder is equal to πr²h, where r represents the radius of a circle on either the top/bottom of the cylinder and h represents the height. Here, the radius is given as 5 and the height as 8, so our volume is
πr²h = π (5)² h= π(25)(8) ≈ 628.3
First divide 3.5 by 2 which equals 1.75. Then do 1.75*3 which equals 5.25. So he drinks 5.25 liters in one hour.
All sides of a square/cube are the same. Since this is a cube, you'll find the volume by "cubing" (get it?) 4.4m.
4.4³ or 4.4 * 4.4 * 4.4 = 85.184m³ but you can round that to 85m³
I hope that helps!
