Find the lateral area of the right prism with height 0.3 dm, if the base of the prism is Isosceles trapezoid with bases of 3 cm and 5 cm, and legs of 4 cm.
The lateral area of that prism consists of 4 rectangles. h = 0.3 dm = 30 cm. The lateral area: A = ( a + b + c + c ) · h A = ( 5 + 3 + 4 + 4 ) · 30 A = 16 · 30 = 480 cm² Answer: The lateral area of the prism is 480 cm².
