Solid geometry is concerned with three-dimensional shapes. Some examples of three-dimensional shapes are cubes, rectangular solids, prisms, cylinders, spheres, cones and pyramids. We will also discuss some nets of solids.
Cubes
A cube is a three-dimensional figure with six matching square sides.
The figure above shows a cube. The dotted lines indicate edges hidden from your view.
If s is the length of one of its sides, the
Volume of the cube = s3
Since the cube has six square-shape sides, the
Surface area of a cube = 6s2Rectangular Solids
In a rectangular solid, the length, width and height may be of different lengths.
The volume of the above rectangular solid would be the product of the length, width and height that is
Volume of rectangular solid = lwh
Surface area of rectangular solid = 2(lw + wh + lh)
