Rectangular Prism Calculator

If you are looking for a web tool that can help you calculate the volume and surface area of a rectangular prism, you might want to check out xcalculator. This tool is a free online calculator that can handle various geometric shapes, including rectangular prisms. In this blog post, we will show you how to use this tool to find the volume and surface area of a rectangular prism in a few simple steps.

A three-dimensional structure with six rectangular sides is known as a rectangular prism. A rectangular prism's volume is the sum of its length, breadth, and height. A rectangular prism's surface area is the sum of the areas of its six sides. To find the area of a rectangular face, you multiply its length and width.

To use this tool to find the volume and surface area of a rectangular prism, you need to enter the values of its length, width, and height in the corresponding fields. You can choose the units of measurement from the drop-down menus. This tool will automatically convert the units and display the results in cubic units for volume and square units for surface area. You can also see the formulae and steps used by this tool to perform the calculations.

Here is an example of using this tool to find the volume and surface area of a rectangular prism with length 10 cm, width 5 cm, and height 8 cm.

Go to

Enter 10 in the length field, 5 in the width field, and 8 in the height field. Choose centimeters (cm) as the unit for all three dimensions.

Click on the Calculate button. This tool will display the results as follows:

Volume = 400 cm^3

Surface Area = 340 cm^2

You can also see the formulae and steps used by this tool to calculate the volume and surface area of the rectangular prism. Click on the Show Steps button to expand the details.

Volume = length * width * height

Volume = 10 * 5 * 8

Volume = 400 cm^3

Surface Area = 2 * (length * width + length * height + width * height)

Surface Area = 2 * (10 * 5 + 10 * 8 + 5 * 8)

Surface Area = 2 * (50 + 80 + 40)

Surface Area = 2 * 170

Surface Area = 340 cm^2

This tool is a handy web tool that can save you time and effort when dealing with geometric calculations. You can use it to find the volume and surface area of a rectangular prism, as well as other shapes such as cubes, cylinders, cones, spheres, pyramids, etc. You can also use it to perform other types of calculations such as algebra, trigonometry, statistics, etc. This tool is easy to use, fast, and accurate.
