Question

I have to write a mathematical report, but I have never written one; as all the reports that I have written where about scientific reports. It is about situation that I am a coffee owner, and when I take the coffee out and serve it I get too many complaints that it is too cold. (Does anyone known any laws, equations, and or tips to write a mathematical report please.) Thank You
(p.s: The coffee cups are all the same material but in different sizes; also what assumptions should I be making from errors I should be expecting?)
