Unit ConversionUnit Conversion Ratio To convert a measurement given in one unit of measure to another unit of measure, a unit conversion ratio can be used. A unit conversion ratio is a fraction equal to 1.
22.
Unit ConversionUnit Conversion Ratio Examples of unit conversion ratios taken from the table on the previous slide are: The conversion factor can be written with either value in the numerator or the denominator. For example:
23.
Unit ConversionUnit Conversion Ratio When converting between units of measure, it is best to write the conversion factor as follows: • The numerator of the ratio consists of the required unit of measure (the unit to which you want to convert). • The denominator of the ratio consists of the given unit of measure (the original units in which the measurement was taken).

Find the SA of a Rectangular Solid A rectangular solid has 6 faces. Top They are: Top Bottom Front Right Back Side Front Right Side Left Side We can only see 3 faces at any one time. Which of the 6 sides are the same? Top and Bottom Front and Back Right Side and Left Side
38.
Surface Area of a Rectangular Solid We know that Each face is a rectangle. Top and the Formula for finding the area of a Right rectangle is: Side A = lw Front Steps: Find: Area of Top Area of Front Area of Right Side Find the sum of the areas Multiply the sum by 2.The answer you get is the surface area of the rectangular solid.
39.
Find the Surface Area of the following:Find the Area of each face: 12 m 2 Top 5m A = 12 m x 5 m = 60 m Top Right Side8m Front Front 8m A = 12 m x 8 m = 96 m 2 5m 12 m 12 m 2 2 2 2Sum = 60 m + 96 m + 40 m = 196 m Right 2 Side 8m A = 8 m x 5 m = 40 m 2 2Multiply sum by 2 = 196 m x 2 = 392 m 5m 2 The surface area = 392 m
