KEY NOTES<\/strong>!<\/p>\n\n\n\n

Definition of Volume<\/strong>: Volume is the amount of space inside a 3-dimensional object. It’s like how much water or air something can hold.<\/p>\n\n\n\n

Calculating Volume:<\/strong> <\/p>\n\n\n\n

Rectangular Solid or Cuboid = l \u00d7 w \u00d7 h (l= Length , w = Width, h = Height)<\/p>\n\n\n\n

Cube = a3<\/sup>( a = Length of edge or side)<\/p>\n\n\n\n

Cylinder = \u03c0r2<\/sup>h (r = Radius of the circular base, h = Height)<\/p>\n\n\n\n

Prism = B \u00d7 h (B = Area of base, (B = side2<\/sup> or length.breadth) ,h = Height)<\/p>\n\n\n\n

Counting Unit Cubes<\/strong><\/p>\n\n\n\n

To find the volume of a shape, count how many unit cubes fit inside it. Arrange them neatly and count them one layer at a time.<\/p>\n\n\n\n
