Volume of a Cube | How to Calculate the Volume of a Cube? | Examples
A cube is a solid box whose every surface is a square of same area. Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of edges 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will
Volume of a Cuboid | Volume of Cuboid Formula | How to Find the Volume
Cuboid is a solid box whose every surface is a rectangle of same area or different areas. A cuboid will have a length, breadth and height. Hence we can conclude that volume is 3 dimensional. To measure the volumes we need to know the measure 3 sides.
Units of Length Conversion Charts | Units of Length Conversion Table
Units of length conversion charts are discussed here in metric units of length and customary units of length: In math when we use length, we know that the standard unit of length is ‘Metre’ which is written in short as ‘m’. A metre length is divided into 100 equal parts.

Unit of Mass or Weight | Unit Weights for Measuring | Common Balance
We know the main standard unit of mass or weight is kilogram which we write in short as ‘kg’. 1000th part of this kilogram is gram which is written in short as ‘g’.
Units for The Measurement of Capacity |Measurement of Capacity| Litre
We know that the two main units for the measurement of capacity are liter and milliliter. In short liter is written as 'l' and milliliter as 'ml'. As for measuring mass we have made several measures to weigh the different masses as 1kg, 500g, 250g, 200g, etc.
