Quick what is the volume 5.7g multipled by length times width times hight. Make sure you multiply it by itself 3 times.

Again for the volume 16.1g multipled by length times width times hight.
Again make sure you multiply it by itself 3 times.

And for the volume 34.4g multipled by length times width times hight.
Again make sure you multiply it by itself 3 times.

And last one the volume 26.9 grams multiple by length times width times hight.
Again make sure you multiply it by itself 3 times.

The answer is celsius

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
