There are different types of solids that are classified based on their shapes. The different types of solids are as follows:. We all know that geometry is the subject that studies about shapes and figures. There are two types of shapes around us – geometrical shapes and non geometrical shapes. Geometrical shapes are the shapes that have predefined properties explained for that particular type of shape. While, a non geometrical shape is not predefined and does not have common properties. The classification of geometrical figures on the basis of dimensions is as follows -(1) lesser than/b>Zero dimensional shape – A point (2) One dimensional shape – A line having a length as its dimension (3) Two dimensional shapes – Having length and breadth as two dimensions. For example – square, triangle, rectangle, parallelogram, trapezoid, rhombus, quadrilateral, polygon, circle etc (4) Three dimensional shapes – With length, breadth and width (height) as three dimensions. For example – cube, cuboid, cone, cylinder, sphere, pyramid, prism etc (5) Higher dimensional shapes – There are few shapes in expressed in dimensions higher than 3, but we usually don’t study them in middle-level mathematics Solid is among among one of the major states of matter. It’s characterized by. structural rigidity and resistance to change of shape or volume. In geometry, the structure that’s in three (even higher) dimension, are known as solids or geometric solids. The study of the properties, volume and surface area of solid objects is called as solid geometry. Let us go ahead and focus more on study of geometrical solids .
