- You should hand in your answers on paper. Answers may be written in blue or black ink, or you may type your answers. For TASK 3, you will need to hand in your model as well as answers on paper.
- Presentation of your project will be considered when marking.
- Good luck and have fun!
Task 1: History of measurement
Write a page (250 to 300 words) about the development of measures of length from ancient times through to the imperial system and the metric system.
Be sure to include a list of ALL of your references.
Your description must be written in your own words, so be careful not to (accidentally or on purpose) plagiarize any of your references. [12]
Task 2: The five rand coin
For this part of the project, you will need to find yourself a new five rand coin.
- Measure each of the following dimensions of the coin in millimeters (correct to 1 decimal place) and convert each of your answers to centimeters (correct to 2 decimal places):
- the diameter of the whole coin, D (2)
- the diameter of the inner gold circle, d (2)
- the height or thickness, h (2)
Figure 1 
- Now calculate each of the following, carefully showing all your working:
- the total surface area of the coin (in cm2). Hint: remember to include the top of the coin, the bottom of the coin AND the sides of the coin. (4)
- the total volume of the coin (in cm3). (3)
- the volume of the inner gold disk (in cm3). (3)
- the volume of the silver ring (in cm3). (2) [18]
Task 3: Building a random object
For the last task of this project, you need to do three things:
- Using the net supplied, build the three dimensional object shown below by folding it carefully along the fold lines and gluing it together on the glue flaps. (8)
Figure 2 
- Determine the total surface area of the object you have built. (6)
- Determine the volume of the object that you have built. (6) [20]
