The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters. What is the volume of the pyramid in cubic centimeters?

The volume of the square-based pyramid is

The volume of a pyramid is given by

where

The area of the square base, , is calculated as follows

substitute the value of , and () into the volume formula to calculate the pyramid's volume

Therefore, the volume of the pyramid is

volume = 13500

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid =

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume =

            =

            = 13500

volume = 13500

The volume of the pyramid is 13500 .

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.
