यह टॉपिक Geometry सेक्शन की तैयारी को मज़बूत करता है। What is a Cuboid? A cuboid, also known as a rectangular prism, is a three-dimensional shape with six rectangular faces. It has:

• • Length (l): The distance between its ends.

• • Width (w): The distance between its sides.

• • Height (h): The distance between its top and bottom faces.

The volume VVV of a cuboid is calculated as V=l×w×hV = l \times w \times hV=l×w×h. The surface area AAA of a cuboid is calculated as A=2lw+2lh+2whA = 2lw + 2lh + 2whA=2lw+2lh+2wh. Importance of Cuboids in Competitive Exams
