AT A GLANCE

¾ The surface of a three-dimensional shape is called its face.
¾ The line segment where the faces meet is called an edge.
¾ The corner where two edges intersect is called a vertex.
¾ A polyhedron is a 3D shape made up of polygons only.
¾ Cube, cuboid, pyramid, prism, sphere, cone, cylinder are some of the common 3D shapes.
¾ A net of a 3D shape is its skeleton outline in 2D, which can be folded to obtain the given
3D shape.
¾ Depending upon the direction from where a solid is viewed we have the front view, side
view and top view of a solid.

MENTAL MATHS

1. The following are the nets of a die (cube). Insert suitable numbers in the blank squares so that
the sum of numbers on the opposite faces is 7.
