    Study Notes

    Cube

    • A cube is a three-dimensional shape with six square faces. All edges of a cube are equal in length.
    • Volume of a cube: Volume = side³ (where 'side' is the length of one edge)
    • Surface area of a cube: Surface Area = 6 * side²
    • Example: If a cube has a side length of 5 cm, its volume is 5³ = 125 cubic cm, and its surface area is 6 * 5² = 150 square cm.

    Rectangle

    • A rectangle is a two-dimensional shape with four sides and four right angles.
    • Opposite sides of a rectangle are equal in length.
    • Area of a rectangle: Area = length × width
    • Perimeter of a rectangle: Perimeter = 2 × (length + width)
    • Example: If a rectangle has a length of 8 cm and a width of 4 cm, its area is 8 × 4 = 32 square cm, and its perimeter is 2 × (8 + 4) = 24 cm.
