- 5. Why do we need to measure?
- 6. 01 Example: If the clear distance between 2 posts is 4 meters, how many CHB’s will be used for the first layer where each CHB = 0.40 M?
- 7. 01 Example: If the clear distance between 2 posts is 5 meters, how many CHB’s will be used for the 2nd layer where each CHB = 0.40 M?
- 8. KINDS OF MEASUREMENT 1. Scalar quantity 2. Vector quantity
- 10. 01 What is the area of this rectangle? 2m 4m A= L x W
- 11. 01 What is the area of this rectangle prism? V = L x W x H
- 12. 01 CONVERSION
- 13. Why is there need for converting units?
- 16. Sample Solutions in Conversion: A. Foot to inches 5 ft. = _____ inches
- 17. b. Inch to feet 36 inches = _____ feet
- 18. b. Centimeter to millimeter 40 cm = _____ millimeters
- 19. d. Inch to centimeter 10 inches = _____ centimeter
- 21. If the space of two post is 5 meters, how many pieces of CHB are needed for 5 layers where each CHB is 0.08 m?
- 23. 2 foot = ______ cm 24 foot = ______ inches 5 meter = ______ inc 28 inches = ______cm
Editor's Notes
- Lets define MEASUREMENT AND CALCULATION
- to help us determine how much material is needed for a certain piece of work. WE NEED TO MEASURE THE DISTANCE BETWEEN TWO POSTS TO DETERMINW HOW MANY CHB WOULD FIT IN FOR ONE LAYER.
- = 4m /.40 =10 Therefore 10 pcs of CHB that will be used for one layer
- = 5m /.040M =12.5 chb used Therefore 25 pcs of CHB that will be used for 2nd layer
- SCALAR QUANTITY Only the magnitude or amount of quantity. VECTOR QUANTITY - Only the magnitude but also the direction Here we will deal only with scalar quantity. As far as measuring work is concerned, we will be dealing only with measurement of LENGTH, AREA and VOLUME.
- Area – quantity that expenses the extent of two-dimensional surface or shape. Only the dimension and area itself is computed. VOLUME – three-dimensional space enclosed by some boundaries like area, volumes also can be computed after measuring the necessary dimension.
- To work with things that vary in size, we can convert between small and large size measurement quickly through the help of a measuring system.
- Metric system – are measure through METER (LENGTH); kilograms (MASS); second (TIME) English system – imperial units – are measured through INCHES, FEET, YARDS, POUNS, OUNCE.
- Solution: Multiply 5ft by 12 inches / ft = 60 inches or 60’’
- Solution: Divide 36 inches by 12 inches / feet = 3 feet or 3’
- Solution: Multiply 40 cm by 10 mm / cm = 400 millimeter or = 400 mm
- Solution: Multiply 10 inches by 2.54 cm / inh = 25.4 centimeters or 25.4 cm
- 5 m / 0.08 m = 312.50 pcs.
- 60.96 cm Note multiply the length value by 30.48
