The Golden Gate Bridge is a suspension bridge spanning the Golden Gate,
the opening into the San Francisco Bay from the Pacific Ocean. It connects the
city of San Francisco on the northern tip of the San Francisco Peninsula
and a portion of the southfacing Marin County headlands near the small bayside
town of Sausalito, and is located at 37Â° 49â€²12â€³N, 122Â° 28â€²43â€³W.
The entire bridge including the approach spans is 1.7 miles long; the distance
between the towers ("main span") is 4200 feet, and the clearance below the
bridge is 220 ft at mean higher high water. The two towers rise 746 feet above
the water. The diameter of the main suspension cables is 36 inches. (Wikipedia)
Given the measure above complete the conversion of miles to kilometers, feet to
meters, and inches to centimeters.
Measuring volume of a regularly shaped object
Volume is the amount of space that something occupies. The volume of a regularly
shaped objects such as a flower box is measured by using the formula width (W)
times height (H) times length (L).
What would be the volume of a box 3 meter by 1 meter by 5 meters (W x H x L).
The units would be represented by cubic meters or m^{3}?
Measuring volume of a regularly shaped object
Irregularly shaped objects volume is determined by using a technique called
displacement. A beaker contain 100 ml of water. If we place a Christmas
ornament into the beaker and the water level rises to 110 ml. What is the
volume of the ornament.
Measuring mass
What device would you use to measure mass?
Measuring weight
What would you use to measure the weight of 2 liter bottle of Mountain Due?
Calculating density
Use the density found in the ornament above and calculate its density if the
mass is 5 kg.
