cuboid.
A cuboid has 8 vertices A, B, C, D, E, F, G and H represents vertices of the
cuboid in fig (1).
By observation, the twelve edges of a cuboid can be grouped into three
groups such that all edges in one group are equal in length, so there are
three distinct groups and the groups are named as length, breadth and
height.
CUBE SHAPE
Properties of Cube
• It has square-shaped faces.
• The angles of the cube in the plane are at a right angle.
• Each face of the cube meets four other faces.
• Each vertex of the cube meets three faces and three edges.
• Opposite edges of the cube are parallel to each other.
Surface Area of Cuboid and Cubes
The surface area of a cuboid is equal to the sum of the areas of its six
rectangular faces.
