Definitions
imperial units
measurement units commonly used in the US and some industries in Canada.
ie. inch, foot, yard, mile, nautical mile
unit analysis
the method of converting units and measuring them in different units
ie. 5 feet= 150 cm
SI measurement system
a system of units based on the power of 10
ie. meters, kilograms, seconds
apex
the vertex farthest from the base of an object
example of an apex is above
right pyramid
an object that has one face that is a polygon and other faces that are triangles with a common vertex
an example of a right pyramid is below
right cone
an object with one circular base and one vertex
i.e. ice cream cone
slant height
the distance from a point on the perimeter of the base of a cone to the apex of the cone
see above for example
lateral area
the surface area of an object not including its bases
see below for example
sphere
an object where every point on the surface of the object is the same distance from the centre of an object
see example below
