BAL Given composite solid, is a rectang doubar prism Cylinder, on a 1764 to cylinder radices v= 6H height of cylinder heeft and prism has 5 lakran surfaces . de rectagle, Lਆਂ 12 ਮਖ width w=oH to find lateral surface area I Now da Alta AL = laterau sufore area of Cylinder A = 25rh 1 = 2XTX 674 А, 2 bғT & A1=4815) fr Az=Laterou surface area of 5 rectangles is A2 = 5XLXW - 52784 = 140 ft? Total lateral surface area = Araz = 481 +140 = 150.84140 = 290.8 FL The lateral surface area is about | 2908) souare feet

To find total suntace area just add top surface of cylinder ine, area of circle. The top circle area of cylinder which also covers area of top suntace of prism. Total sintace area = 2trh+ 19r2+ 5x(49W = 48T7+ ITXC6R+57732 = 844+140 = 403.9 ff2 The suntace area is about 1403-9) For Square feet.
