What we have learnt
- Surface area is the total area covered by the surface of a 3D solid.
- Volume is the amount of space enclosed within the solid.
- Different geometrical shapes like cubes, cuboids, cylinders, cones, spheres, and hemispheres have specific formulas for calculating surface area and volume.
Key Concepts
-
Term: Surface Area
Definition: The total area covered by the surface of a three-dimensional solid.
-
Term: Volume
Definition: The amount of space enclosed within a solid figure.
-
Term: Cube
Definition: A three-dimensional shape with equal-length edges, with specific formulas for surface area and volume.
-
Term: Cuboid
Definition: A three-dimensional shape with rectangular faces, defined by its length, breadth, and height.
-
Term: Cylinder
Definition: A three-dimensional shape with two parallel circular bases connected by a curved surface.
-
Term: Cone
Definition: A three-dimensional shape with a circular base that tapers to a point called the apex.
-
Term: Sphere
Definition: A perfectly round three-dimensional shape where every point on the surface is equidistant from the center.
-
Term: Hemisphere
Definition: Half of a sphere, often cut by a plane passing through its center.
