Lesson 4 Homework Practice Surface Area Of Prisms Site

Consider a triangular prism with a triangular base having sides of 3 cm, 4 cm, and 5 cm, and a height of 6 cm. The base is a right-angled triangle.

Let’s walk through the process you should apply to every homework problem.

Add up the lengths of all sides of the base. lesson 4 homework practice surface area of prisms

Is it a square, rectangle, triangle, or other polygon?

Surface area isn’t just a classroom exercise. When you complete , you’re building skills used in: Consider a triangular prism with a triangular base

A rectangular shipping box has length 12 in, width 8 in, and height 6 in. Find the surface area of the box (assuming no overlaps).

The sum is your total surface area in square units (e.g., cm2c m squared in2i n squared 3. Triangular Prisms: The "Five-Face" Rule Add up the lengths of all sides of the base

The surface area of a prism consists of the areas of its two polygonal bases and the areas of its rectangular faces. The formula for the surface area (SA) of a prism is:

Here, "Area of the base" refers to the area of one of the polygonal bases, "Perimeter of the base" is the perimeter of one of the polygonal bases, and "Height" is the distance between the two bases, which is also the height of the rectangular faces.

Try these on your own. Answers are at the end.
