What is the surface area of your cake pan? (top of cake pan is open)

Is it okay to use your cake pan for this recipe?

Answer 1

Your cake pan is going to have the same volume and surface area as the recipes cake pan, go ahead and use it ;)

Answer 2

Volume of recipes cake pan is v= l×w×h
v = 9×11×2 = 198 in cubed

volume of your cake pan is
V = 10×10×2 = 200 in cubed

surface area of recipe pan
is the sum of the areas of each side... 18, 18, 22, 22, 99 = 179 in sq

surface area of your pan is sum of area of sides... 20, 20, 20, 20, and 100 = 180 in sq

You can use your pan because the volume and surface area are greater than the recipe pan.
