Please help me with this :)

36

Step-by-step explanation:

The length is 4

the width is 3

and the height is 2

There are only 2 shapes (not in total) that you need to multiply

For the first one is the bottom and top (one of the shapes), This will make 12 for the bottom. Added with the top makes 24

For the second shape it is 6, since there is 4 of them, multiply them up, and you get 24

24 + 12 =36

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
