Triangular prism formula surface area4/12/2024 ![]() Therefore, 84 square feet of cloth is required for a tent. 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. Use our online triangular prism calculator to find the surface area within a blink of eye. 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. Surface Area ( Base × Height ) + ( ( Side1 + Side2 + Side3 ) × Prism Height ) Generally, the surface area of a triangular prism formula is equal to twice the base area plus the perimeter of the base times the height or length of the solid. Solution: As we know, Total Surface Area (TSA) (b × h) + (s1 + s2 + s3) × l, here, s1. = 6 \(\times\) 4 + (5 + 6 + 5) \(\times\) 15 Find the total surface area of a triangular prism given in the figure. 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.
