Rectangular Prism Calculator
Calculate the volume, surface area, and diagonal of a rectangular prism with ease.
What is the Rectangular Prism Calculator & How does it work?
A rectangular prism is a three-dimensional shape with six faces, all of which are rectangles. It has three dimensions: length (l), width (w), and height (h). The volume (V) of a rectangular prism can be calculated using the formula:The surface area (SA) of a rectangular prism is the sum of the areas of all six faces. It can be calculated using the formula:The diagonal (d) of a rectangular prism can be calculated using the Pythagorean theorem in three dimensions:
V = l times w times h
l = length, w = width, h = height
SA = 2(lw + lh + wh)
l = length, w = width, h = height
d = sqrt{l^2 + w^2 + h^2}
l = length, w = width, h = height

Frequently Asked Questions
How do I calculate the volume of a rectangular prism?
Multiply the length by the width by the height to find the volume.
What is the formula for the surface area of a rectangular prism?
The surface area is calculated as 2 times (length times width plus length times height plus width times height).
Can this calculator handle decimal measurements?
Yes, you can enter decimal values for length, width, and height to get precise calculations.
How do I find the diagonal of a rectangular prism?
Use the formula d = sqrt(l^2 + w^2 + h^2) where l is length, w is width, and h is height.
Is this calculator suitable for large dimensions?
Yes, it can handle large numbers, but ensure your input values are accurate to get reliable results.
What units should I use when entering the dimensions?
Use consistent units (all in meters, all in inches, etc.) for length, width, and height.
Can this calculator be used for non-rectangular prisms?
No, this calculator is specifically designed for rectangular prisms with six rectangular faces.
