Work out the surface area of the triangular prism. The regular triangular prism has a base edge of 8.6 dm and a height of 1.5 m. Example 1: finding the surface area of a triangular prism with a right triangle. Calculate the surface and volume of this prism.įind the volume and surface of a prism with a height of 120 mm, the base of which is a right isosceles triangle with a leg length of 5 cm. Its base is an equilateral triangle whose height is 3 cm. The regular triangular prism is 7 cm high. Determine the volume of the prism if its surface is 468 cm². The height of the prism is 2cm smaller than the larger base leg. 2 triangular sides have a base of 30 millimeters and height of 27.3 millimeters. A rectangular prism with a length of 30 millimeters, width of 18 millimeters, and height of 9 millimeters. The base of the perpendicular prism is a rectangular triangle whose legs lengths are at a 3:4 ratio. Helen wants to find the surface area of the solid pictured on the left, so she constructs a net of the solid pictured on the right. (base edge length and base triangle height length). The height of the prism is v = 5.5 m.Ĭalculate the volume and surface area of the body that is created by cutting out a three-sided prism of the same height from a cuboid with dimensions of 10 cm, 15 cm, and 20 cm, whose base is a right-angled triangle with dimensions of 3 cm, 4 cm, and 5Ĭalculate the volume and surface area of a triangular prism if it is given: a = 6.8 dm.Va = 4 dm. Calculate its volume.Ĭalculate the volume and surface of a triangular prism whose base is a right triangle with sides a = 3m, b = Va = 4m, and c = 5m. To find the area of the rectangular sides, use the formula A lw, where A area, l length, and h height. A triangular prism has three rectangular sides and two triangular faces. The area of the largest sidewall of its surface is 130 cm², and the body's height is 10 cm. The surface area of any prism is the total area of all its sides and faces. The base of the perpendicular triangular prism is a right triangle with a leg length of 5 cm. a) Find the height of the prism b) Calculate the surface of the prism c) What percentage of the cubĬalculate a triangular prism if it has a rectangular triangle base with a = 4cm and hypotenuse c = 50mm, and the height of the prism is 0.12 dm. What is the volume of a prism?įind the volume and surface of a triangular prism with the base of a right triangle, the network of which is 4 cm 3 cm (perpendiculars) and nine centimeters (height of the prism).Ī right-angled prism, whose base is a right triangle with leg a = 3 cm and hypotenuse c = 13 cm, has the same volume as a cube with an edge length of 3 dm. What is the surface of the prism if its volume is 54 cubic centimeters?ĭetermine the volume and surface of a triangular prism with a height of 12.4 cm the base is a right triangle with 6 cm and 8 cm.Ī triangular prism has the base of a right triangle with 6 dm and 8 dm legs and a hypotenuse of 10 dm. The base of a vertical triangular prism is a right triangle with legs 4.5 cm and 6 cm long. What is its volume cm³? And the surface cm²? A triangular prism when divided has five faces, two triangular and three rectangular faces. The triangular prism has a base in the shape of a right triangle, the legs of which are 9 cm and 40 cm long. Calculate the volume and surface of a triangular perpendicular prism with the base of a right triangle.Ĭalculate the surface area and volume of a three-sided prism with a base of a right-angled triangle, if its sides are a=3cm, b=4cm, c=5cm and the height of the prism is v=12cm. The lengths of the base legs are 7.2 cm and 4.7 cm, and the height of the prism is 24 cm. Lateral Area: The lateral area of a prism or pyramid is the combined area of its lateral faces. Some basic terminology for this section can be found below. For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm 3 and S in mm 2.īelow are the standard formulas for surface area.We encourage you to watch this tutorial video on this math problem: video1 video2 video3 Related math problems and questions: Cones It is assumed that the reader has basic knowledge of the above solids and their properties from the previous unit entitled Solids, Nets and Cross Sections. And you probably just forgot to multiply your equation by ½: 7 × 3 × 4 84. Quiz Key points A prism has a constant cross-section. This means that the equation for the 1st problem wouldve been: ½ × 7 × 3 × 4 42. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. The equation for finding the volume of a triangular prism is: ½ × b × h × l Volume. Units: Note that units are shown for convenience but do not affect the calculations.
