    Study Notes

    Solid Figures

    • A solid figure is a three-dimensional object or shape with length, width, and height, occupying space and having a volume measurement.
    • Any object that you see in real life is a solid figure, including figures drawn on paper or modeled using computer software.

    Types of Solid Figures

    • Prisms: three-dimensional solid figures with at least two identical sides that face each other, examples include rectangular prisms and triangular prisms.
    • Cubes: a box made of six squares of the same size that all meet at ninety-degree angles, also a type of rectangular prism.
    • Cones: a solid figure consisting of a round base and a curved side that points towards the top and converges in a single point called the apex.
    • Pyramids: a solid figure with a base and three or more triangular faces extending upwards and meeting at a single point called an apex, examples include triangular pyramids and rectangular pyramids.
    • Spheres: a ball that is perfectly round, with only one surface, no faces, no edges, and no vertices.
    • Cylinders: a tube shape with circle or oval bases on each end, with two faces and three surfaces.

    Characteristics of Solid Figures

    • Faces: flat surfaces of a solid figure, also called sides.
    • Edges: where two faces meet.
    • Vertices: where the angles of two or more faces meet, also called corners.

    Real-Life Examples of Solid Shapes

    • Rectangular prisms: smartphones, laptops, dining tables, and boxes.
    • Cubes: dice.
    • Cones: traffic cones, pointy birthday hats, and ice cream cones.
    • Pyramids: Pyramids of Giza, tents, and roofs of houses.
    • Spheres: basketballs, volleyballs, baseballs, and the Earth (approximately).
    • Cylinders: toilet paper rolls, paper towel rolls, grain silos, water tanks, food tins, and round drink coasters.
