RELATIONSHIPS OF THE VOLUMES OF SOLID FIGURES


RELATIONSHIPS OF THE VOLUMES OF SOLID FIGURES


 M6MEIVa-95 - determines the relationship of the volume between a rectangular prism and a

pyramid; a cylinder and a cone; and a cylinder and sphere.

______________________________________________________________________________

Determining the relationship of volume between a rectangular prism and a pyramid:

  • The volume of a rectangular prism is length x width x height.
  • The volume of a pyramid is (length x width x height)/3.
  • A rectangular pyramid has one-third the volume of a rectangular prism with the same base and height.

Determining the relationship of volume between a cylinder and a cone:

  • The volume of a cylinder is π x radius² x height.
  • The volume of a cone is (π x radius² x height)/3.
  • A cone has one-third the volume of a cylinder with the same base and height.

Determining the relationship of volume between a cylinder and sphere:

  • The volume of a cylinder is π x radius² x height.
  • The volume of a sphere is (4/3) x π x radius³.
  • A sphere has 1.5 times the volume of a cylinder with the same radius and height.

Other important notes:

  • The volume of a three-dimensional shape is the amount of space it takes up.
  • Formulas for finding the volume of shapes are used to determine the relationship between the volumes of different shapes.
  • Understanding the relationship between the volumes of different shapes can be helpful in many real-life situations, such as calculating the amount of water a container can hold or the amount of soil needed for a garden.
