The perimeter is a characteristic of a 2-dimensional object. A 12 by 13 by 5 sounds like a 3-dimensional object which would not have a perimeter.
the perimeter means the length around an object. so your perimeter around the object you have must be 8.
in geometry, perimeter is the length around the outside of an object.
Perimeter = 4*13 = 52 units of measurment
Perimeter = 6*13 = 78 units
perimeter
The concept of a perimeter does not make sense for a solid object.
If it's a square, the perimeter is 24.
Perimeter is the distance around an object and area is the amount of space/volume in an object (square,rectangle,triangle)
A square has equal length sides, so each side is 13 in. The perimeter is the distance of the 4 sides added together. The perimeter is: 13 + 13 + 13 + 13; which is 52 in.
Perimeter is around the object youre measuring and area is the inside.
You determine the perimeter of an object by adding up the lengths of all sides.
