The diagram shows a prism. The cross-section of the prism is an isosceles triangle. The lengths of the sides of the triangle are 13 cm, 13 cm and 10 cm. The perpendicular height of the triangle is 12 cm. The length of the prism is 8 cm. Work out the total
13 x 8 = 1048 x 10 = 800.5 x 10 x 12 = 60
SA = 104 + 104 + 80 + 60 + 60 SA = 408 cm2
