A prism is a three-dimensional geometric figure with two identical and parallel faces called bases. These bases can be any polygon, like triangles or rectangles, and the other faces, known as lateral faces, are parallelograms formed by connecting the corresponding vertices of the bases.
Prisms are essential in geometry and can be visualized as shapes like a Toblerone chocolate bar or a glass prism refracting light into a rainbow. They help us understand space, volume, and the world around us through their properties and formulas.

Volume formulas
Cube
a – base lenght
Rectangular prism
l – lenght, w – width, h – height
Triangular prism
V = area of triangle x height of prism
a – length of one side of the triangle,
h – length of an altitude drawn to side H – distance between the triangular faces.
