Total time = number of cakes *2÷ the number that can be baked in each pot * the baking time on each side. When the time is not an integer, approximate it with the method of entering one. For example, when the number of cakes is 4, each pot contains 3 cakes and each side is baked for 2 minutes, according to the formula, 4*2÷3*2≈6 points. When only two cakes are baked in a pot, the total time = the time to bake one side * the number of sheets.

A formula that uses mathematical symbols to express the relationship between several quantities in natural sciences such as mathematics, physics, chemistry and biology. It is universal and applicable to all similar problems. In mathematical logic, a formula is a formal grammatical object to express a proposition, but the proposition may depend on the free variable value of the formula.
