Answer» TSA of cuboid =2[lb×bh×lh]TSA of cube= 6(side)2CSA of cuboid=2(l+b)hCSA of cube=4a2CSA of cylinder=2πrhTSA of cylinder=2πr(r+h)CSA of cone=πrlTSA of cone=πr(r+l)SA of sphere=4πr2CSA of hemisphere=2πr2TSA of hemudphere=3πr2Volume of cuboid=l×b×hVolume cube=(side)3Volume cylinder=πr2rhVolume of cone =1/3πr2hVolume of hemisphere=2/3πr3Volume of sphere=4/3πr3
• Total surface area of a cuboid = 2[lb + bh + lh]• Total surface area of a cube = 6(side)2• Lateral surface area of a cuboid = Area of walls of a room = 2(l + b) × h• Lateral surface area of a cube = 4a2• Curved surface area of cylinder = 2πrh• Total surface area of a cylinder = 2πr(r + h)• Curved surface area of a cone = πrl• Total surface area of a cone = πr(r + l)• Surface area of a sphere = 4πr2• Curved surface area of a hemisphere = 2πr2• Total surface area of a hemisphere = 3πr2• Volume of a\'cuboid = l × b × h• Volume of a cube = (side)3• Volume of a cylinder = πr2rhSOLIDS AND THEIR SURFACE AREASThe bodies occupying space are called solids, such as a cuboid, a cube, a cylinder, a cone, a sphere, etc.These solids have plane or curved surfaces.SURFACE AREA OF A CUBOID AND A CUBEThe outer surface of a cuboid is made up of six rectangles. If we take the length of the cuboid as l, breadth as b and the height as h, thenSurface area of a cuboid = 2[lb + bh + hl]Surface area of a cube = 6a2Note:\xa0I. Sometimes a cuboid does not have bottom and top faces. is called the lateral surface area. II. Lateral surface area of a cuboid is 2(l + b)h. III. Lateral surface area of a cube is 4a2. IV. Surface area of a cuboid or cube means total surface area.
