Examples, solutions, videos, and worksheets to help grade 7 students learn how to find the surface area of prisms using the formula SA = LA + 2B = Ph + 2B where:

SA is the surface area of the prism.

LA is the lateral area of the prism.

P is the perimeter of the base.

h is the height of the prism.

B is the area of the base.

A prism is a three-dimensional solid shape with two identical flat faces (bases) on opposite sides, connected by lateral faces. A right prism has bases that are parallel to each other. The lateral faces are perpendicular (at a 90-degree angle) to the bases and form rectangles.

Finding the Surface Area of a Right Prism

A right prism is a three-dimensional solid with two parallel and congruent bases, and other faces that are parallelograms (usually rectangles).

To find the surface area of a right prism, you need to find the area of all the faces and sum them up.

Here’s a step-by-step guide:

Steps to Find the Surface Area of a Right Prism

- Identify the Shape of the Bases: Determine the shape of the bases (e.g., triangle, rectangle, pentagon, etc.).
- Calculate the Area of the Bases: Use the appropriate formula for the shape of the bases to calculate their area.
- Find the Perimeter of the Base: Calculate the perimeter of one of the bases.
- Calculate the Lateral Surface Area: Multiply the perimeter of the base by the height of the prism.
- Sum the Areas: Add the areas of the two bases and the lateral surface area to find the total surface area.
