What Does the Right Rectangular Prism Calculator Calculate?
The calculator can determine:
Volume
The amount of space inside the prism.
Formula:
Volume = Length ร Width ร Height
Surface Area
The total area of all six faces.
Formula:
Surface Area = 2(LW + LH + WH)
Where:
- L = Length
- W = Width
- H = Height
Lateral Surface Area
The area of the four side faces excluding the top and bottom.
Formula:
Lateral Surface Area = 2H(L + W)
Space Diagonal
The longest straight-line distance between two opposite vertices.
Formula:
Diagonal = โ(Lยฒ + Wยฒ + Hยฒ)
Inputs Required
To use the calculator, users typically enter:
Length
The longest side of the prism.
Width
The shorter side of the base.
Height
The vertical measurement from base to top.
These three dimensions are sufficient to calculate all major properties of a right rectangular prism.

Right Rectangular Prism Formulas Explained
Volume Formula
The volume measures how much space exists inside the prism.
Formula:
V = L ร W ร H
Example:
Length = 8 m
Width = 4 m
Height = 3 m
Volume:
V = 8 ร 4 ร 3
V = 96 cubic meters
Surface Area Formula
Surface area represents the total exterior area.
Formula:
SA = 2(LW + LH + WH)
Example:
SA = 2(32 + 24 + 12)
SA = 2(68)
SA = 136 square meters
Space Diagonal Formula
The space diagonal connects opposite corners through the interior.
Formula:
D = โ(Lยฒ + Wยฒ + Hยฒ)
Example:
D = โ(64 + 16 + 9)
D = โ89
D โ 9.43 meters
Practical Example
Imagine a storage box with dimensions:
- Length = 10 feet
- Width = 5 feet
- Height = 4 feet
Volume
10 ร 5 ร 4 = 200 cubic feet
Surface Area
2(50 + 40 + 20)
= 2(110)
= 220 square feet
Diagonal
โ(100 + 25 + 16)
= โ141
โ 11.87 feet
The calculator performs all these calculations instantly.
