# Three-Dimensional Shapes

Here students will get a chance to learn about three-dimensional shapes for class 2 maths. They also know about the term’s faces, edges, and corners of different 3d shapes in geometry

In this learning concept, the students will also learn about the different types of 3d shapes:

• Properties of Cube
• Properties of Cuboid
• Properties of Sphere
• Properties of Cylinder Shape
• Properties of Cone Shape

Each concept is explained to class 2 maths students using illustrations, examples, and mind maps. You can assess your learning by solving the two printable worksheets at the page’s end.
Download the three-dimensional shape worksheet for class 2 and check the solutions for the concept of 3d shapes provided in PDF format.

Three-dimensional shapes are not flat shapes. These shapes occupy space. It means that we can touch and feel them. These shapes have three dimensions including length, depth/height, and width. Three- dimensional shapes are called solid shapes also.

Although these three-dimensional shapes are different, still these shapes have some common properties.

• Faces: A face is a flat or curved surface of a solid shape.
• Edges: An edge is where two faces meet.
• Corners: A corner is where two or more edges meet.

Here we will discuss the following solid shapes.

• Cube
• Cuboid
• Cone
• Cylinder
• Sphere

### Properties of Cube

A cube is a three-dimensional shape that has square-shaped faces. All the edges of a cube have the same length.

Following are some examples of cubes that can be seen in our surroundings.

Dice, rubric cubes, sugar cube,...etc are examples of the cube.

### Properties of Cuboid

A cuboid is a three-dimensional shape that has rectangular faces. Opposite edges of a cuboid have the same length.

Following are some examples of cuboids that can be seen in our surroundings.

Bricks, lunch boxes, cartoon boxes,...etc are examples of cuboids.

### Properties of Sphere

A sphere is a three-dimensional shape that has no corners and no edges. A sphere has only one curved face.

Following are some examples of spheres that can be seen in our surroundings.

Globe, an orange, a football,...etc are examples of spheres.

### Properties of Cone Shape

A cone is a three-dimensional shape that has one corner and one circular edge. A cone has one circular flat face and one curved face.

Following are some examples of cones that can be seen in our surroundings.

Traffic cone, ice cream cone, carrot, ...etc are examples of cones.

### Properties of Cylinder Shape

A cylinder is a three-dimensional shape that has no corner and two circular edges. A cylinder has two circular flat faces and one curved face.

Following are some examples of cylinders that can be seen in our surroundings.

Battery, drum, gas cylinder, ...etc are examples of cylinders.

### Sliding and Rolling Objects

Sliding and rolling are two properties that can be found in solid shapes.

• Sliding: When an object moves on a surface without rolling, then we call it sliding.
• Rolling: When an object moves over a surface by turning over and over again, then we call it rolling.

The solid shapes that have flat faces can slide and the solid shapes that have curved faces can roll.

• Cube, cuboids have flat faces. So, they can slide.
• Cone, cylinder, and sphere have curved faces. So, they can roll.
• But the cone and cylinder both have circular flat faces also. So, they can slide also.
