A Rectangular Prism is a three dimensional shape with six faces. All angles are right angles.

The faces consist of two equal ends, two equal sides and an equal top and bottom

(Note - in the calculator below only the top is refered to, but the bottom is included in the calculations)

Calculations can be saved to a table by clicking the "Add to Table" button he first time the button is clicked)

There is also the option to create a PDF document

*End surface area = h x w*

*Side surface area = h x l*

*Top surface area = w x l*

*Total surface area = 2 x ((h x w) + (h x l) + (w x l))*

*Volume = h x w x l*

Have you ever wondered why people use rectangle calculators when they can do the required calculations on their own within minutes? Well, sometimes the calculations are so easy that you can solve the problems within seconds but at certain times, they become dreary and lengthy. Using a math calculator focused on rectangle calculations can allow you to save a lot of time and utilize it somewhere else.

Rectangles are not just a shape that you drew in your classroom as a child. In real world we use so many objects that are rectangular; ever wondered how they came into being? What all calculations went behind them? Be it the bed you are sleeping on, the copy or book you are reading or the table you study on, everything is a rectangle. Calculating these figures in everyday life is not an easy task and this is the reason why people often use a rectangle calculator.

Let's learn more about the rectangle and its prominence in our everyday life to understand the utility of a rectangle calculator.

In Mathematics, a rectangle is a 2-D shape enclosed by 4 sides in which all the interior angles are right angles (90 degrees). The opposite sides of a rectangle are identical and are parallel to each other.

There are numerous definitions of a rectangle. In Euclidean plane geometry, a rectangle can be defined as a quadrilateral whose all the four angles are right angles.

We can also call it a parallelogram having a right angle.

A rectangle is one of the most common shapes that we encounter every day. There are numerous properties of a rectangle. Some of the most interesting and important properties are listed below-

- A rectangle is cyclic which means all the corners of the rectangle lie on a single circle.
- All the corner angles of a rectangle are equal (90 degrees).
- The sides of a rectangle meet each other at right angles which makes it rectilinear.
- There are two diagonals of a rectangle that bisect each other (i.e., intersect each other at midpoints).
- The opposite sides of a rectangle are identical and are parallel to each other.

It is easy for anyone to remember the formulas related to the calculation of a rectangle such as the perimeter of a rectangle or the area of a rectangle. But performing the calculations aimed at making a new object, planning a new construction or ploughing vast rectangular fields is not a cakewalk in reality.

You could imagine if you are asked to calculate the area of a field when its length and breadth are given, how long it will take you to solve the problem?

This is the time when you need a rectangle calculator that may save you time and perform the required calculations in seconds.

The perimeter of a rectangle can be defined as the total distance around the outside of a rectangle. It can be calculated by adding up all the sides of the rectangle simultaneously.

The formula for calculating the perimeter of a rectangle is given by-

P= 2(l+b)

Where:

- P is the perimeter of the rectangle,
- 'l' is the length of the rectangle,
- And 'b' is the breadth of the rectangle.

The area of a rectangle can be defined as the number of square units it takes to fill a rectangle completely. The formula for calculating the area of a rectangle is given by-

A= l*b

Where:

- A= Area of the rectangle,
- 'l' is the length of the rectangle,
- And 'b' is the breadth of the rectangle.

Calculating rectangles in everyday life can be tedious and time consuming in the absence of a rectangle calculator. Irrespective of the fact that people know the properties and the formulas related to a rectangle, they prefer using a rectangle calculator in order to do accurate calculations and refrain from wasting much time on manual calculations and rechecking them.

Rectangles often appear in our day to day lives. The blackboard in your school, the swimming pool in your backyard, your mobile phones, doors, windows, books, tables, beds, everything is a rectangle. If you are asked to find the area or perimeter of these shapes, all you need to do is to enter the given values in the respective fields of the rectangle calculator and you will get your solution within minutes.

To sum it up, a rectangle calculator is a quick tool to compute all rectangle-based calculations in a split second. The rectangle calculator provides convenience, accuracy and increases productivity at work.
