1 Chapter 1 Measurement Math Chapter 1 Measurement Sections : Goals: Converting between imperial units by unit analysis Converting between SI units Converting between SI and imperial units Imperial units inch, foot, yard, mile SI units metric system (I) Converting between imperial units by unit analysis How do we set a conversion up to be solved by unit analysis? Example: Using the scales in the table below, use the units only to create a single line where each stated unit is converted to the indicated unit. (a) yards to feet = yds x 1 ft. = 12 in. 1 yd. = 3 ft. 1 yd. = 36 in. 1 mi. = 1760 yd. 1 mi. = 5280 ft. From the scale above, what units must be placed in the numerator (top) and denominator (bottom) so that yards cancel and feet remain?
2 Chapter 1 Measurement Math Sometimes conversions may involve more than one scale 1 ft. = 12 in. 1 yd. = 3 ft. 1 yd. = 36 in. 1 mi. = 1760 yd. 1 mi. = 5280 ft. (b) = mi x x miles to inches From the scale above, what units must be placed in the numerators (top) and denominators (bottom) so that miles cancel and inches remain? Example: Estimate the amount of wire that feeds through the floor joists. (a) length in inches (b) convert to feet Converting by Unit Analysis 1 ft. = 1 =
3 Chapter 1 Measurement Math Relationships between units: Example 1: Convert 100 yd to: (a) ft. (b) inches 1 ft. = 12 in. 1 yd. = 3 ft. 1 yd. = 36 in. 1 mi. = 1760 yd. 1 mi. = 5280 ft. Example 2: A sunken ship is discovered by sonar to be in ft of water. Convert this depth to miles. Example 3: Convert yds to yards, feet and inches. Example 4: The perimeter of a ceiling in a room is measured for the purpose of installing crown molding. The perimeter of the ceiling is 272 in. (a) What is the perimeter of the ceiling in feet? (b) The cost of crown molding is $3.75/ft.. Determine the cost of ordering crown molding to install in the room.
4 Chapter 1 Measurement Math (II) Converting between SI units The smallest metric measurement on the ruler below is the. How many divisions make up 1 cm? Answer: When we use metric measurements for determining length it is based on increments of 10. SI units Abbreviation Relationship between units millimeter mm centimetre cm 1 cm = 10 mm metre m 1 m = 100 cm kilometre km 1 km = 1000 m Example 5: Convert each length to the indicated measurement cm = mm m = km mm = cm m = cm 5. 6 km = m cm = m
5 Chapter 1 Measurement Math (III) Converting Imperial Units to SI units 1 foot = 12 inches 1 yard = 3 feet 1 mile = 1760 yards 1 inch = 2.54 centimetres 2.5 centimetres 1 mile 1.6 kilometres Example 6: Convert each measurement to the nearest tenth. (a) 8 in = cm (b) 264 mi = km (c) 7 ft = cm (d) 1 yd = mm (e) 6 ft. 7 in. = cm (f) 4 yd. 2 ft. 2 in = m Questions: Page #7,8ab,10b,11a,15,17,18 Page # 4,5,6,7a (in part (ii) delete ft and in), 10,12,14,15

8 Chapter 1 Measurement Math Section 1.4: Surface Area of Right Pyramids and Right Cones Pyramids: are named or described by the shape of its base. SA of pyramids = SA of base + SA of lateral sides (triangles) NOTE if the base polygon of a pyramid is regular (all sides =) then all lateral triangles are congruent Example 1: Determine the surface area of the regular triangular pyramid (regular tetrahedron) Sketch the tetrahedron net diagram 13 yd
9 Chapter 1 Measurement Math The Right Pyramid A three dimensional object that has Triangular faces (lateral faces) Base is a polygon (many sides) Point on top is called the apex S represents slant height (the height Of the triangular face) h is the height of the pyramid (the Perpendicular distance from the Apex to the center of the base) The Lateral Area, AL, is the area Of the exposed triangles (surface area without the base) Example 2: Determine the lateral area and the surface area of the square pyramid Sketch the net diagram
