Cuboid

घनाभ

Cuboid is a three-dimensional solid with six rectangular faces, studied in Class 9 Mathematics under Surface Area and Volume. Students learn to identify its length, breadth, and height, and use these dimensions to calculate the total surface area, lateral surface area, and volume. The topic also develops understanding of nets, unit conversion, and practical applications such as finding the material needed to cover a box or the space it can contain.
