# All About 3D Shapes - What is a Cube?

Learning shapes lays the foundation for understanding geometry, and it also helps kids improve their visual-spatial skills. After learning 2D shapes, kids will move on to learn 3D shapes. Unlike 2D shapes which are flat, 3D shapes have depth. 3D shapes have three dimensions: length, width, and height. Kids are expected to identify and describe 3D shapes in kindergarten. They should be able to sort, describe and name 3D objects in the environment in grade 1. And they should be able to describe the features of 3D objects in grade 2. Cubes are one of the most basic of 3D shapes. A cube is a 3-dimensional solid object bounded by 6 identical square faces, and it looks like a box.
This worksheet aims to introduce cubes to kids. A cube is a 3-dimensional shape bounded around by 6 squares, which are called faces. A cube has 6 faces, 12 edges, and 8 vertices/corners. All faces are squares of the same size. All edges are of the same length. The total surface area of a cube is the sum of the area of the 6 identical squares. Some common examples of cubes around us include boxes, dices, Rubik's cubes, ice cubes, sugar cubes, and toy blocks. Parents could help kids improve their geometry knowledge with the interesting facts of cubes provided in this worksheet.
