I just really need someone to explain his method to make the 4 pancakes and 10 pancakes You want to make 10 pancakes

a. How much flour do you need

10:4 = ? : 6

Flour = 10/4 = ?/6

10 pancakes = 6 +6 + 3= 15 spoonful’s of flour
How much milk do you need
b. 10 pancakes = 1/4 + 1/4 + 1/8? = 3/16 pints

Also something is wrong in his recipe

if the right cylinder and right square prism have the same volume, then all of the dimensions must be the same. therefore, the radius of the cylinder and the side lengths of the square base must be the same as well.

Step-by-step explanation:

basically if the volume is the same then the dimensions are the same no matter what so the radius and the square have to be equal if they're the same volume.
