Should students be required to know the difference between perimeter, area, and volume in order to get a job in their adult life?
What can you use to find the perimeter of a shape?
Perimeter is the total distance around the outside of a shape. Area is the total space inside a shape. Volume is the amount of space a 3D shape takes up.
Perimeter, Area, and Volume Explained for 5th Grade Students
Perimeter: The distance around the outside of a shape. Area: The measure of the size of a surface or region. Volume: The measure of the size of a three-dimensional object.
Concepts:
The volume of a cube is equal to the length of its edges cubed, and the area of a cube is equal to the length of its edges squared. The volume of a sphere is two-thirds the product of its surface area and its radius. The perimeter of a circle is equal to the circumference of the circle, which is calculated by multiplying the diameter of the circle by pi.
