Study Notes

Measuring Lengths, Area, Surface Area, Capacity, and Mass

This is a Grade 7 Mathematics topic.
The objectives are to illustrate measuring, identify and use metric system prefixes (kilo-, hecto-, deka-, deci-, centi-, milli-), and convert and solve problems involving length, capacity, and mass measurements.
Ancient Egyptians used body parts for measurements (span, palm, digit, foot, cubit, pace).
Span: distance from little finger tip to thumb tip of outstretched hand.
Palm: distance across the base of the four fingers that form the hand.
Digit: thickness or width of the index finger.
Foot: length of a foot.
Cubit: distance from middle fingertip to elbow.
Pace: distance of one full step.
The inch (used today) is derived from thumb width (according to Romans).
A yard, as decreed by King Henry I of England, is the distance from the tip of his nose to the end of the middle finger of his outstretched arm.

Units of Measurement (Metric)

The basic unit of length is the meter (m).
Metric prefixes indicate multiples or fractions of a base unit. Common prefixes include kilo-, hecto-, deka-, deci-, centi-, and milli-.
The table below shows the values and symbols for the prefixes.

Prefix	Symbol	Value
kilo-	k	1000
hecto-	h	100
deka-	da	10
deci-	d	1/10 or 0.1
centi-	c	1/100 or 0.01
milli-	m	1/1000 or 0.001

Rules for converting between metric units:
- To convert from a larger unit to a smaller unit, multiply by a power of ten (move decimal to the right).
- To convert from a smaller unit to a larger unit, divide by a power of ten (move decimal to the left).

Units of Measurement (Customary)

12 inches = 1 foot
3 feet = 1 yard
5 feet = 1 pace
264 paces = 1 furlong
8 furlongs = 1 mile
24 furlongs = 1 league

Formulas

Perimeter of a Rectangle: P = 2l + 2w or P = 2(l + w)
Circumference of a Circle: C = πd or C = 2πr (where π ≈ 3.14)
Area of a Rectangle: A = lw
Area of a Parallelogram: A = bh
Area of a Trapezoid: A = ½h(b₁ + b₂)
Area of a Circle: A = πr²
Area of a Square: A = s²
Area of a Triangle: A = ½bh
Area of a Rhombus: A = bh

Solid Shapes

Different shapes have specific names for geometric regions (faces, edges, vertices).
Prisms (with parallel bases), Pyramids (with a base), Cylinders (with circular bases).

Surface Area

Surface area is the sum of the areas of all the faces of a three-dimensional figure.
Surface Area of a Cube: SA = 6s²
Surface Area of a Rectangular Solid: SA = 2lw + 2hw + 2hl
Lateral Area of a Regular Pyramid: L = ½lp
Surface Area of a Regular Pyramid: S = L + B
Lateral Area of a Right Circular Cylinder: L = 2πrh
Surface Area of a Right Circular Cylinder: S = L + 2B = 2πrh + 2πr²
