Perimeter is the outside length of an object...three-d or not. So, if you want to find out the outisde length of an object/perimeter, you will have to know the measure of one or two sides (depends on a shape) and add it.
If you know the perimeter, there is no need to find it again.
You determine the perimeter of an object by adding up the lengths of all sides.
The perimeter
Add all the sides up
The concept of a perimeter does not make sense for a solid object.
If it's a square, the perimeter is 24.
To find perimeter you would add all of the sides of your object together to get the final result.
Add up all the sides of the object you're trying to find the perimeter for.
Add sides together
Perimeter is the distance around an object. Area is the total amount of space inside the object. Length is the the measurement of one side of the object. Length is added up to find the perimeter. Length is multiplied to find the area.
Add all the sides up
add all the sides together
The concept of a perimeter makes sense only in the context of a 2-dimensional object (or a sphere).
The lengths of each of its sides.
