1.1 Imperial MeasurementsMFM2P

In the beginningBack in the day (1000s of years ago) when people built things themselves, it wasnt necessary to measure things because everyone did it themselves.I need a bolt as wide as thumb

What you talkin bout Willis?However, projects became more complicated, it became necessary to have others work different parts, therefore they had to standardize measurement.Sir, I dont know what your thumb looks likemoron

Birth of ImperialismSo they decide to take the most popular guy, measure his thumb and call it an inch. This guy was the King!An inch was the width of a thumbA foot was the size of the kings foot, which eventually became 12 inches.A yard was the distance from the tip of a man's nose to the end of his outstretched arm. Eventually, 3 feet became a yard

Other systemsThe British empire used this method to devise measurements for mass, volume and time. For instance a pound was equal to 7002 troy grains

Other countries developed their own units of measure7001? Thats stupid! A pound should be 7002Your sands are no match for our stones! Whats a troy grain? We use wheat seeds

A new dayEventually (in the 1800s), the French developed the Metric System

In the 1970s many commonwealth (former British colonies) switched to the metric system.

Imperial SystemsToday, the entire world is metric, except for the US, Myanmar and Liberia

The Imperial EmpireUnfortunately, the US has a HUGE influence on our culture. This influences the way we communicate and think about various systems of measurement.

= (2 x 12) + 7= 3 feet x 12 inches 1 footConverting Feet to Inches1 foot = 12 inches3 = 3 feet= 362 7 = 2 + 7= 24 +7= 31= 8.5 x 12 8.5 = 8.5 feet= 102Page 3 Question 3

Converting Inches to Feet1 foot = 12 inches71 inches =How many times does 12 go into 71?71 inches = 5 feet + ??? inches71 inches = 5 feet + 11 inches5 = 6071 -60 = 11Page 3 Question 4a

The school gymnasium floor needs to be resurfaced. Hardwood flooring costs $6 per square foot plus $2.50 per square foot for installation. The gym measures 180ft by 220ft.

a) Size of gym = (length) (width)= (220 ft) (180 ft)= 39 600ft2 Therefore the gym is 39 600ft2.

b) Cost to buy hardwood = ($6.00/ft2) (39 600ft2)= $237 600The cost of the hardwood is $237 600.

c) Cost of Installation = ($2.50/ft2) (39 600ft2)= $99 000Therefore the cost of installation is $99 000
