Volume Of A Rectangular Solid

A rectangular solid is also called a rectangular prism or a cuboid.

In a rectangular solid, the length, width and height may be of different lengths.

The volume of the above rectangular solid would be the product of the length, width and height that is
Volume of rectangular solid = lwh

How To Find The Volume Of A Rectangular Prism Or Cuboid?

The formula for the volume of a cuboid is l × w × h = lwh, where l is the length, w is the width and h is the height of the rectangular prism. This video will give two examples of finding the volume of a rectangular prism.

Examples:

1. Find the volume of a rectangular prism with sides 25 feet, 10 feet and 14 feet.
2. Find the volume of a rectangular prism with sides 5.4 inches, 7.5 inches and 18.3 inches.

Volume Of A Prism

A prism is a solid that has two parallel faces which are congruent polygons at both ends. These faces form the bases of the prism. The other faces are in the shape of rectangles. They are called lateral faces. A prism is named after the shape of its base.

When we cut a prism parallel to the base, we get a cross section of a prism. The cross section has the same size and shape as the base.

The volume of a right prism is given by the formula:
Volume of prism = Area of base × length
V = Al
where A is the area of the base and l is the length or height of the prism.

Volume Of A Cylinder

A cylinder is a solid that has two parallel faces which are congruent circles. These faces form the bases of the cylinder. The cylinder has one curved surface. The height of the cylinder is the perpendicular distance between the two bases.

The volume of a cylinder is given by the formula:
Volume = Area of base × height
V = π r²h
where r = radius of cylinder and h is the height or length of cylinder.

Volume Of A Hollow Cylinder

Sometimes you may be required to calculate the volume of a hollow cylinder or tube.

Volume of hollow cylinder

where _R_ is the radius of the outer surface and _r_ is the radius of the inner surface.

Volume of hollow containers - cylinder and cone
How you can find the volume of a hollow cylinder and a cone using the formula of volume of prism and pyramid?

Examples:

1. Given a pipe with length = 12cm, outer diameter = 2m and thickness = 40cm. Calculate the amount of concrete used?
2. Given that an ice-cream cone has a diameter of 65mm, height of 15cm and thickness of 2mm. Calculate the volume of wafer in the cone.

Volume Of A Cone

A cone is a solid with a circular base. It has a curved surface which tapers (i.e. decreases in size) to a vertex at the top. The height of the cone is the perpendicular distance from the base to the vertex.

The volume of a cone is given by the formula:
Volume of cone = 1/3 × Area of base × height
V = 1/3 πr²h
where r is the radius of the base and h is the height of the prism.

Volume of a Pyramid

A pyramid is a solid with a polygonal base and several triangular lateral faces. The lateral faces meet at a common vertex. The height of the pyramid is the perpendicular distance from the base to the vertex. The pyramid is named after the shape of its base. For example a rectangular pyramid or a triangular pyramid.

The volume of a pyramid is given by the formula:
Volume of pyramid = 1/3 × Area of base × height
V = 1/3 Ah where A
is the area of the base and h is the height of the pyramid.

Volume of a Sphere

A sphere is a solid in which all the points on the round surface are equidistant from a fixed point, known as the center of the sphere. The distance from the center to the surface is the radius.

Volume of sphere = 4/3 πr³
where r is the radius.
