![]() P = 2 + 2 + 2 + 2 2 P = 8 2 20 Then, multiply P by the height of the prism. Task cards 1- 12 focus on finding the volume of rectangular prismsTask cards 13 - 24 focus on finding the surface area. Use these volume and surface area task cards as a whole class activity, a math station or in small groups. To find the lateral surface area, you can calculate the area of each lateral face, or you can use this formula: LA = Ph Perimeter of the Base Height of prismįind the lateral surface area. Students will practice finding the surface area and volume of rectangular prisms with this set of 24 task cards. Lateral, lateral, lateral is the label, label, label… Example: Find the surface area of prism shown in the figure. We mark the length l, width w, and height h of the prism and use the formula, Area of top and bottom face 2 lw. If we were to unwrap a gift, the amount of wrapping would be equal to the surface area of the object it was covering. Cuboids or rectangular prisms have 6 rectangular faces. Lateral area is the surface of a solid, excluding the bases. The surface area is like the minimum amount of wrapping paper we need to prep a gift for its surprise reveal. 10) A rectangular-shaped box has the following dimensions: 12 yards, 8 yards, and 18 yards. The box is 10 inches tall, 8 inches wide, and 6 inches long.

The following diagram shows the formula for the surface area of a rectangular prism. S = Ph + 2B S = 10(5) + 2(6) S = 62 units²Įric wants to wrap his mom’s Christmas present. Examples, videos, worksheets, stories, and solutions to help Grade 6 students learn how to find the surface area of a prism. Develop fluency in finding the surface area of a rectangular prism, a 3-dimensional shape with six faces. B = lw B = 3(2) 2 3 B = 6 Finally, plug your calculations for P and B into the formula for surface area. Surface Area of a Rectangular Prism Worksheets. Area of the Base S = Ph + 2B Perimeter of the Base Height of prismįirst, find P. Step 2: Now click the button Solve to get the rectangular prism surface area Step 3: Finally, the surface area of a rectangular prism will be displayed in the output field. ![]() You can also use a formula to calculate total surface area of prisms. How to Use the Surface Area of a Rectangular Prism Calculator The procedure to use the surface area of a rectangular prism calculator is as follows: Step 1: Enter the length, width and height in the input field. Calculate the total surface area of the prism. Julie Wright found another One solution is 2 units by 3 units by 6 units. ![]()
