Drag the ruler to measure the diagram, each length should be measured to the nearest centimetre. Give your answer in square metres to the nearest square metre.įind the surface area of a trapezoidal prism based on the views drawn to scale below.
Calculate the area of canvas needed for the tent (excluding the bottom of the prism as that is where the ground sheet goes). The height of the tent is 3.2m, the width of the tent (at the triangular ends) is 3.5m, the sloping edges of the tent are each 3.64m an the length of the tent is 7.8m. The frame for a large tent is in the shape of an isosceles triangular prism. Calculate the surface area of the prism if AB = 8cm, BC = 9cm and CD = 12cm. The cross section of a semi-transparent prism is a right angled triangle as shown in the diagram. The area of its octagonal faces is 278.9cm 2 and the sides of the octagons are each 7.6cm.įind its surface area correct to one decimal place.įind the surface area of a triangular prism if the area of its cross section is 51cm 2, its length is 37cm and the three sides of the triangular ends add up to 33cm. The area of its pentagonal faces is 43cm 2 and the sides of the pentagons are each 5cm.Īn octagonal prism has a length of 9.8cm.
