As we know,Total Surface Area (TSA) = (2 × Base Area) + (Perimeter × Height), here base Area = 12 cm2, perimeter = 16 cm, height = length = 7 cm∴ TSA = (2 × 12) + (16 × 7)= 136 in2

A prism is a member of the polyhedron family consisting of two identical and parallel polygonal bases. The bases are connected by flat faces forming a uniform cross-section.

As we know,Total Surface Area (TSA) = (2 × Base Area) + (Perimeter × Height), here base area = 36 cm2, perimeter = 30 cm, height = 11 cm∴ TSA = (2 × 36) + (30 × 11)= 402 cm2Lateral Surface Area (LSA) = Perimeter × Height∴ LSA = 30 × 11= 330 cm2

A prism is a three-dimensional soild object having two identical and parallel shapes facing each other. The identical shapes are called the bases. The bases can have any shape of a polygon such as triangles, square, rectangle, or a pentagon. The diagram below shows a triangular prism.

Find the total and lateral surface area of a rectangular prism whose base area is 36 cm2 , perimeter is 30 cm, and height is 11 cm.

A prism can also be classified into regular or irregular based on the uniformity of its cross-section. It can be right or oblique, depending on the alignment of its bases.

Depending on the base, a prism can be of different shapes. Some common shapes are: triangular, rectangular, square, pentagonal, hexagonal, heptagonal, octagonal, and trapezoidal. For example, a triangular prism has a triangular base and a square prism has a square base, here are some more shapes:

In general, a prism refers to a transparent solid used to refract or scatter a beam of white light. It is a commonly used instrument in physics.
