A rectangle-shaped prism is a three-dimensional shape, having actually six faces, wherein all the deals with (top, bottom, and also lateral faces) that the prism room rectangles such that every two opposite side faces are identical. Like all three-dimensional shapes, a rectangular prism also has volume and also surface area. A rectangular prism is also known as a cuboid. Let united state learn more about a rectangle-shaped prism in addition to the recipe to discover its volume and also surface area.

What IsRectangular Prism?
A rectangular prism is a prism who bases (both its optimal face and bottom face)are rectangles.It has 6 deals with in complete out ofwhich there are 3 bag of the same opposite faces. I.e., every 2 opposite faces are similar in a rectangular prism. It has three dimensions, length, width, and height. Some instances of a rectangle-shaped prism in genuine life are rectangular tissue boxes, school notebooks, laptops, fish tanks, huge structures such together cargo containers, rooms,storage sheds, etc. In the figure below, you have the right to see exactly how a rectangular prism looks like and how its network (the shape developed by it once its deals with are opened) watch like.
Types ofRectangular Prisms
There space two species of rectangular prisms that space classified depending on the form of the side encounters (or) the edge made by the side deals with with the base.Right rectangular prismOblique rectangle-shaped prism
A right rectangle-shaped prism has its side faces perpendicular to each of the bases. In this,all side encounters are rectangles. One oblique rectangular prism is a prism the is no a right rectangle-shaped prism and its side deals with are parallelograms. In general, a rectangular prism without any kind of specifications is a right rectangular prism.
Properties ofRectangular Prism
Here room the properties of a rectangular prism the follow the definition.A rectangular prism has actually 6 faces, 8 vertices, and also 12 edges.Its base and top are constantly rectangles.The side deals with are rectangles for a right rectangular prism conversely, the side encounters of an oblique rectangular prism space parallelograms.It has 3 dimensions, length, width, and height.
Formulas ofRectangular Prism
In this section, we will find out the recipe of the volume and surface area of a rectangle-shaped prism. For both that these, permit us consider a rectangular prism of length 'l', width 'w', and also height 'h'. Along these dimensions, let united state assume the 'l' and also 'w' are the size of the base. Below are the formulas because that the volume and surface area of a rectangular prism.
Let us see how to derive this formulas.
Volume of rectangle-shaped Prism
The volume of a rectangle-shaped prism is the an are that is inside it. We recognize that the volume of any type of prism is acquired by multiplying its basic area by its height. Here,The elevation of the rectangle-shaped prism = h
Thus, the volume the the rectangle-shaped prism, V = lw× h = lwh.
Surface Area ofRectangular Prism
There room two types of surface area the a rectangle-shaped prism, one is the complete surface area (TSA) and also the various other is the lateral surface ar area (LSA).TSA the a rectangular prism is the amount of the areas of all of its faces.LSA of a rectangle-shaped prism is the sum of the locations of every its side faces (no bases).
We have the right to calculate the locations of the side deals with of a rectangular prism utilizing its network as shown below.
Using the above figure,
The full surface area (TSA) the a rectangle-shaped prism
= The amount of locations of every faces
= lw + lw +wh + wh + hl + hl
= 2 (lw + wh + hl)
The lateral surface ar area (LSA) of a rectangular prism
= The sum of areas of next faces
= wh + wh + hl + hl
= 2 (wh + hl)
We will see the applications of these volume and also surface area formulas of a rectangle-shaped prism in the ar below.

Example 2:A gift is pack in a rectangular box (rectangular prism)of size 15 in, 10 in, and 8 in and it needs to it is in wrapped v gift paper. Just how much gift paper is compelled to wrap the gift box?
The size of the provided gift box are,
length, together = 15in
width, w = 10in
height, h = 8in
To find the amount of gift record required, we require to discover the total surface area that the box.
