Study Notes

Perimeter and Area Calculations

The perimeter is calculated by summing all sides of the figure.
The area is calculated by multiplying the length by the width of the figure.
Perimeter is measured in units, while area is measured in squared units.

Conversions

1 km = 1000 m
1 m = 100 cm
1 cm = 10 mm
1 kg = 1000 g
1 g = 100 cg
1 cg = 10 mg

Other Conversions

1 foot = 0.3048 meters
1 mile = 1.609 kilometers
1 inch = 2.54 centimeters
1 yard = 0.9144 meters

Rates

Rates are expressed as ratios.
Ratios can be simplified to their lowest terms by dividing both the numerator and denominator by their greatest common factor.

Measuring Tools

Measuring tapes are used to measure length.
The units on a measuring tape can be inches or centimeters.

Metric Units

The metric system is a decimal system of measurement based on the meter, kilogram, and liter.
Kilometers (km) are used for measuring long distances.
Millimeters (mm) are used for measuring small lengths.
Meters (m) are used for measuring medium lengths.

Appropriate Units

The appropriate unit of measurement for a particular quantity depends on the size of the quantity.
For example, the height of a mountain would be measured in kilometers, while the height of a glue stick would be measured in centimeters.

Volume

Volume is the amount of space a three-dimensional object occupies.
Volume is measured in cubic units such as cubic meters (m³) or cubic feet (ft³).
The volume of a rectangular prism is calculated by multiplying the length, width, and height.
V = l x w x h
