![]() Therefore, 84 square feet of cloth is required for a tent. Heres the most basic formula for triangular prism surface that we can use: Area Length × (a + b + c) + (2 × Base area) or. Since the kaleidoscope is in the shape of a triangular prism, we can use the formula for the surface area to find its height.ĥ76 = 9 \(\times\) 7.8 + (9 + 9 + 9)H ĥ76 – 70.2 = (27)H ![]() It is mentioned that the surface area of the kaleidoscope is 576 \(cm^2\) and the base height is 7.8 cm. Find the height of the kaleidoscope.Īs stated, the length of each side of the kaleidoscope is 7.8 cm. The surface area of the kaleidoscope is 576 \(cm^2\), and its base height is 7.8 cm. Find the length of the triangular prism if its base is 6 cm, altitude is 9 cm and the area is 198. Hence, the surface area of a triangular prism is 264 square centimeters.Ĭathy recently purchased a new triangular kaleidoscope in which the sides are 9 cm long. Find the total surface area of a triangular prism if its base is 5 cm, altitude is 7 cm and length is 8 cm. A prism is a three-dimensional solid with two identical polygonal bases connected by parallelogram lateral faces. The Surface Area of a Prism Formula depends on the shape of the base. A triangular prism is defined as a three-dimensional shape, having its bases as triangles. Calculate the unknown defining side lengths, circumferences, volumes or radii of a various geometric shapes with any 2 known variables. A prism is defined as a 3-dimensional solid object which has identical ends, flat faces, and the same cross-section all along its length. = 6 \(\times\) 4 + (5 + 6 + 5) \(\times\) 15 The surface area of a prism is the sum of the areas of all its faces. Calculator online for a the surface area of a capsule, cone, conical frustum, cube, cylinder, hemisphere, square pyramid, rectangular prism, triangular prism, sphere, or spherical cap. Surface area of a triangular prism = bh + (a + b + c)H ![]() ![]() We can find the surface area of the triangular prism by applying the formula, The height of the triangular prism is H = 15 cm The base and height of the triangular faces are b = 6 cm and h = 4 cm. Find the surface area of the triangular prism with the measurements seen in the image.įrom the image, we can observe that the side lengths of the triangle are a = 5 cm, b = 6 cm and c = 5 cm. ![]()
