Total Surface Area of Prism: 70 sq cm + 56 sq cm + 40 sq cm = 166 sq cm. Using a Formula for Total Surface Area of a Rectangular Prism. EDUCATIONAL MATHS (Accuracy and Clarity).
Total Surface Area of Prism: 70 sq cm + 56 sq cm + 40 sq cm = 166 sq cm. Surface Area of Terminal/End Surfaces: 2 x (5cm x 4cm) = 2 x 20 sq cm (40 sq cm). Scroll down the page for more examples and solutions for the surface area of a rectangular prism. Step 2: Draw a net diagram using the given side length. The following diagram shows the formula for the surface area of a rectangular prism. Step 1: Identify the given side lengths of a rectangular prism.

Surface Area of Lateral/Side Surfaces: 2 x (7cm x 4cm) = 2 x 28 sq cm (56 sq cm). Examples, videos, worksheets, stories, and solutions to help Grade 6 students learn how to find the surface area of a prism. Surface Area Of A Rectangular Prism Formula Finding surface area for all rectangular prisms (including cubes) involves both addition and multiplication. Surface Area of Top and Bottom Surfaces: 2 x (7cm x 5cm) = 2 x 35 sq cm (70 sq cm).
Total Surface Area = The Sum of the Areas of the 3 pairs of Surfaces which combine to make up the Rectangular Prism. Since a Rectangular Prism has 6 Surfaces comprising 3 identical pairs of Surfaces (2 identical Upper and Lower surfaces, 2 identical Lateral/Side Surfaces and 2 identical Terminal/End Surfaces), a simple, easy-to-follow solution to this problem is:
