The solids or Solid Figures are three-dimensional objects. This means is that solid figures have a width, a depth, and a height. For example, look at your computer, laptop, phone, wood table etc.. In the Solids Around Us Video explains different Solids and their properties, watch the video. Solids have a width, a depth, and a height.
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. A cone is a solid figure that has a circular face on one end, called the base, and a point at the other end where the sides meet. I’m pretty sure we have all enjoyed an ice cream cone at one point in our lives. The cone that you put the ice cream in is an example of a cone, and what a delicious example! Some other examples could include a megaphone, a tee-pee tent, or a birthday party hat. In the picture below, we see that a parking cone is another example of a cone.
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. Pictured below is a Rubik’s cube. We see that this is a rectangular prism.
Cubes are just a special case of rectangular prisms. Cubes are solid figures that have six faces . A sphere is a solid figure that is round and has the shape of a ball. For example, a basketball is a sphere. A pyramid is a solid figure that has a polygon as its base on one end, and triangular faces all meeting at a single point on the other end. Many of us have heard of the Great Pyramids of Egypt. These are a perfect example of a pyramid in the world around us. A cylinder is a solid figure that has two circular bases and one curved side.
