topic 9-
units of measurement
KM=M=CM=MM
Perimeter
base x height
perimeter is the distance (or length) around a shape
all sides are equal
Area
measured in cube units
Area of triangle
Base x height x 1/2
You do the equation like you would do in area then divide by 2
The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle.
length x width
Volume
volume is a measure of the amount of space a container takes up
3 dimensional shape
there is space inside
Length x width x height
Measured in cube units
capacity
capacity is a measure of how much a container can hold . we might measure the capacity of a bottle , cup or carton -anything which can hold something else
