What we have learnt
- The area of a polygon can be derived from the areas of its component triangles and trapeziums.
- The surface area of three-dimensional shapes is the total area of all their faces.
- Volume measures the space occupied by a three-dimensional object and is calculated differently for various solid shapes.
Key Concepts
- -- Area
- The measure of the space covered by a two-dimensional shape, typically expressed in square units.
- -- Perimeter
- The total distance around the boundary of a two-dimensional shape.
- -- Surface Area
- The total area of the surface of a three-dimensional object.
- -- Volume
- The measure of the amount of space a three-dimensional object occupies, expressed in cubic units.
- -- Cuboid
- A three-dimensional shape with six rectangular faces.
- -- Cylinder
- A three-dimensional shape with two parallel circular bases connected by a curved surface.
- -- Rhombus
- A type of polygon that is a quadrilateral with opposite sides parallel and all sides equal in length.
