The net of a triangle prism is shown. Use the ruler provided to measure the dimensions of the net to the nearest half centimeter. Which measurement is closest to the total surface area of the triangular prism in the square centimeters?

Step-by-step explanation:

The net of the triangular prims is attached.

Remember, the total surface area refers to the area of each face of the volumetric figure. In this case we have three equal rectangles and two equal triangles.

Remember that the area of a rectangle is just the product of its width and height.

The total surface area is given by the sum of all these areas:

Therefore, the total surface area of the figure is 516 square units.

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.
