Math Quiz Review for Tuesday, February 25, 2014

~ Volume= L. x W. x H.
Ex:
a rectangular prism has measurements of
3 cm (length), 4 cm (width), and 7 cm (height)
To get the volume of this rectangular prism, I multiply:
3 cm X 4 cm X 7 cm = 84 cm3
The volume of this rectangle is 84 cm3
~ How to figure out which side of a prism is the length, width, height:
Length: usually longer than width
Width: usually shorter than length
Height: the line that is sticking up in the air
~Area:  To get the area of something, you multiply one side by the other
Ex:
5cm >
                           7cm


to get the area= 7cm X 5 cm= 35 cm2
~How to get TSA (Total Surface Area):
(W x H) + (H x L) + (L x W) x 2 = TSA (Total Surface Area)
Ex: Example 1

This cube has six congruent faces, each with a length and width of 3 cm.
Area of one face = 3 x 3 cm = 9 cm2
Surface area = 6 sides x 9 cm2 = 54 cm2
~ 1,000 mL = 1 liter
~ 10 mm = 1 cm 
~ 100 cm = 1 meter
~ 10,000 cm2 = 1 m2
~ 1,000 grams = 1 kilogram
~ 100 mm2 = 1 cm2
~ 1mL = 1 cm3 
~ 1 m3 = 1,000 L  
~ 1,000,000 cm3 = 1 m3
