![]() ![]() Solution 2: We have: Apothem length 5 cm Base length 10 cm height 18 cm. Example 2: Find the surface area of the triangular prism if the apothem length 5 cm, base length 10 cm, and height 18 cm. The area of a triangle is calculated by multiplying the base by the height and. Example 2: The perimeter of a triangular prism is 108 units and its lateral surface area is 756 units. The two triangular faces are congruent, meaning they have the same dimensions. ![]() Answer: The lateral area of the given triangular prism 160 cm 2. Thus, the lateral area of triangular prism (a + b + c ) h. Step 1: Copy down the formula for surface area in your notes. The height of the triangular prism 10 cm. So, Surface area of a triangular prism bh + (a + b + c)H. A triangular prism consists of two triangular faces and. To calculate the volume of a triangular prism, find the area of the triangular cross-section and multiply it by the length of the prism (or height of the prism). The surface area of a triangular prism formula (Apothem length x base length) + 3 x (base length x height). Use the formule SA bh +pH to solve for the surface area of a triangular prism. Since the kaleidoscope is in the shape of a triangular prism, we can use the formula for the surface area to find its height. The total surface area of a triangular prism is the sum of all the areas of the faces of the prism. The volume of a triangular prism is how much space there is inside of the shape. Surface area of a triangular prism bh + (a + b + c)H Solved Examples Example 1: Find the surface area of the triangular prism with the measurements seen in the image.
