So, the required area of the wrapping paper is 522 square inches. Surface area of the wrapping paper = Surface area of the laptop box Find the surface area of the wrapping paper that is required to wrap the box. For part 2 of this video, including example 2, as well as many more in. He wants to wrap the box with gift wrapping paper. This video illustrates how to use the formula for Lateral Area of a Rectangular Prism. Lateral Surface Area if a Rectangular Prism by Angel Banks - January 28, 2014. Step 4: ADD the top, bottom, and sides to get the TOTAL. The dimension of the laptop box is 15 inches by 12 inches by 3 inches. Step 3: Multiply the PERIMETER by the HEIGHT to find the total surface area of all the vertical sides. These integrals can be very labor intensive to compute. The surface area of S can be computed with the following double integral: T v t × v s d t d s. Surface area of the rectangular prism = 2 (lb + bh + hl)ħ6 = 2 (5 × 4 + 4 × h + 5 × h ) ģ8 = 5 × 4 + 4 × h + 5 × h Įxample 3: John wants to give a laptop to her mother. plane (also known as the parameter space) that corresponds with S. īase length of the rectangular prism, l = 5 mīase width of the rectangular prism, b = 4 m ![]() If youre trying to find the surface area of a triangular prism, use the formula SA 2a + ph, where a is the area of the triangle, p is the perimeter, and h is the height. ![]() Surface area of the rectangular prism, S = 76 \( m^2\). To find surface area for a rectangular prism, use the formula SA 2ab + 2bc + 2ac, where a is the width, b is the height, and c is the length. So, the surface area of the model is 1110 square inches.Įxample 2: Find the height of the rectangular prism that has a base length of 5 m, base width is 4 m, and surface area is 76 \( m^2\). Surface area of the model = 2 (lb + bh + hl) If a rectangular prism has a length of 5 units, a width of 3 units, and a height of 2 units, then applying our formula, we find that the surface area is S A 2 (5 × 3) + 2 (5 × 2) + 2 (3 × 2). Let’s bring this concept to life with tangible examples. Each rectangular prism has a length, a width, and a height. Height of the rectangular prism, h = 5 in Surface Area of Rectangular Prism Examples. 1.Label the length, width, and height of your rectangular prism. This video lesson will introduce the formula for finding the surface area of a right rectangular prism and how to use it. (Thickness of the model is considered as negligible).īase length of the rectangular prism, l = 20 inīase width of the rectangular prism, b = 18 in The dimensions of the model are: base length is 20 inches, width of the base is 18 inches, and the height of the building is 5 inches.
