Solid Figures

PASAY-M5-Q3-W4-D3

Visualizes and describes solid figures.

Solid figures

are three-dimensional objects, meaning they have length, width, and height. Because they have three dimensions, they have depth and take up space.

Solid Figures

Solid figures are identified according to the features that are unique to each type of solid. Specifically, you can observe the numbers of faces, edges, and vertices, as well as the shape of the base.

PARTS OF SOLID FIGURES

The flat surfaces of a solid figure are its faces, or sides as they are commonly called. The base is the face on which the figure rests. The edge of a solid figure is the line segment where two faces meet. A vertex (plural: vertices) is the corner that is formed where the ends of the line segments of two or more faces meet.

PRISM

A prism is a solid figure that has two congruent parallel faces and any number of sides. In other words, it can have any number of faces, but at least two of them must be parallel. The shape of the two parallel faces can be a triangle, square, rectangle, pentagon, hexagon, or any other kind of polygon. Prisms are named by the shape of their bases.

rectangular prism

A rectangular prism is a solid figure that has six sides, called faces, that are rectangles. This can be thought of as a fancy name for something that has the shape of a cardboard box. Rectangular prisms show up all around us.

Some examples may include a book, a piece of furniture, or a jewelry box.

other prism

Triangular prism and pentagonal prism

Cubes

Cubes are just a special case of rectangular prisms. Cubes are solid figures that have six faces that are all squares of the same size. Since a square is a rectangle, a cube has six faces that are all rectangles, so a cube is a rectangular prism. 

Pyramid

A pyramid has one base and at least three triangular faces. It has edges where faces meet each other at the base, vertices where two faces meet the base, and a vertex at the top where all of the triangular faces meet. A pyramid is named by the shape of its base. 

Pyramid

A triangular pyramid has a triangle-shaped base and three other triangular faces, or four in all.

A rectangular pyramid has a rectangle-shaped base and a square-based pyramid has a square-shaped base. They both have four triangular faces, five faces in all. 

There are solid figures that are bounded by curve surfaces

Cylinder

A cylinder has two circular faces but also no edges or vertices. It is a prism with bases bounded by simple closed curved usually circles.

Sphere

A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. All points on a sphere are the same distance from the center

Cone

A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top. The pointed end of the cone is called the apex, whereas the flat surface is called the base.
