Volume
Volume is the amount of space enclosed by an object or shape, how much
3-dimensional space (length, height, and width) it occupies. A flat shape like triangle, square and rectangle occupies surface on the plane. When we draw a flat shape on a paper, it occupies a certain area of paper. Solid shapes like cube, cuboid and cylinder occupy space. The amount of space occupied by a solid is called its volume.
Solid shape has length, breadth and height.
Plane figures like triangle, quadrilaterals and circles do
not occupy any space because they lie on a plane. But solid figures like those
given below do occupy space.
Every object that occupies space has a volume.
What is volume?
The space occupied by any object is called the volume.
So, the volume of an object is the amount of space occupied by the object.
Volume is measured in "cubic units".
Surface like the page of your book, black board, are called plane surfaces. They do not have any volume but have only area.
A cube is a solid whose length, breadth and height are equal. Therefore, a cube, is taken as the unit of solid to measure the amount of space that a solid occupies.
Consider a cube whose length, breadth and height are 1 cm. The volume of this cube is 1 cubic centimetre. It is written as cu cm or. cc. We call a cube with 1 cc volume a unit cube. We always measure volume in cubic units.
1 cc = 1 cm × 1 cm × 1 cm
For measuring the volume of a solid, we count the number of unit cubes contained by the solid.
Let us see how many cubes are there in the following cuboids.
The cuboid in figure (i) is formed by placing 4 cubes in a row. So, the volume of the cuboids is 4 cu cm.
The cuboid in figure (ii) is formed by 8 cubes. So, the volume of the cuboids is 8 cu cm or 8 cc. The cuboid formed in figure 2 has a length of 4 cm, breadth 1 cm and height 2 cm.
Therefore, the volume of the cuboid = length × breadth × height
= 2 × 1 × 2
= 8 cu cm.

We will discuss here how to find the perimeter of a square. Perimeter of a square is the total length (distance) of the boundary of a square. We know that all the sides of a square are equal. Perimeter of a Square Perimeter of the square ABCD = AB+BC+CD+AD=2 cm+2cm+2cm+2cm
We will discuss here how to find the perimeter of a rectangle. We know perimeter of a rectangle is the total length (distance) of the boundary of a rectangle. ABCD is a rectangle. We know that the opposite sides of a rectangle are equal. AB = CD = 5 cm and BC = AD = 3 cm
Perimeter of a figure is explained here. Perimeter is the total length of the boundary of a closed figure. The perimeter of a simple closed figure is the sum of the measures of line-segments which have surrounded the figure.

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.
