## Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

Full form of 3D is "Three Dimension". Three dimension geometric shapes are the figures which has length, breadth and height.

Examples of 3D geometric shapes: -

• Sphere
• Cylinder
• Cone
• Cuboid
• Cube

 3D Shape Definition Examples Formula Sphere The solid generated by revolving a circular alumina about any of its diameters, is called the sphere. Football, volleyball, etc., Volume = 4/3 πr^3 Surface area = 4π r^2 Cylinder The solid bounded by a circular curved surface and two identical bases. Circular pillars, circular pipes, circular pencils, measuring jars, road rollers and gas cylinder etc., Volume = π r^2 h Curved surface area= 2 π r h Total surface area= 2πr(r + h) Cone The solid generated by the rotation of a right- angled triangle about one of the sides containing the right angle is called a right circular cone. Ice-cream cone, conical vessel, clown’s cap, etc. Volume= (1/3)π r^2 h Curved surface area= πr√( h^2 + r^2) = π r l Total surface area= π r (l + r) Cuboid A solid bounded by six rectangular faces is called a cuboid. Matchbox, chalk box, brick, tile, book, etc., Volume= l * b * h Diagonal=√(l^2+b^2+h^2 ) Total surface area =2(lb+bh+lh) Lateral surface area =2 ( l + b) * h Cube A cuboid whose length, breadth and heights are all equal is called a cube. Dice, ice cubes, sugar cubes etc., Volume= a^3 Diagonal = √3 a Total surface area= 6 a^2 Lateral surface area= 4 a^2
