Final answer:
To follow the recipe for chocolate cake correctly, you will need 236.6 cm^3 of buttermilk, as 1 mL is equivalent to 1 cm^3.
Step-by-step explanation:
To convert the required volume of buttermilk from milliliters (mL) to cubic centimeters (cm3), we can use the fact that 1 milliliter is equivalent to 1 cubic centimeter. The recipe for chocolate cake calls for 236.6mL of buttermilk. Since the conversion is 1:1, you will need the same number of cubic centimeters as milliliters.
Therefore, to follow the recipe correctly, you will need 236.6 cm3 of buttermilk.
