FAQ
How to calculate cuboid volume?
Volume = length × width × height.
How to calculate cuboid surface area?
Surface area = 2 × (length×width + length×height + width×height).
How to calculate the space diagonal?
Space diagonal = √(length² + width² + height²).
How to calculate a parcel volume?
Parcel volume is usually length × width × height; logistics may also apply volumetric weight rules.
Are cuboid and rectangular prism the same?
Generally yes — both describe a six-faced solid defined by length, width and height.
