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. The base of the perpendicular prism is a rectangular triangle whose legs lengths are at a 3:4 ratio. (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. The area of the largest sidewall of its surface is 130 cm², and the body's height is 10 cm. 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.
