Chapter 7: Space

In this topic, an object that has the shape of a cuboid, cube, cone, pyramid, and sphere is used to understand three-dimensional and two-dimensional shapes.

 7.1 Bentuk Tiga Dimensi
• Three -dimensional (3D) shapes are shapes that have length, width and height.

The three-dimensional shapes are as in the table below.

 Example of 3D Shape Cube Cuboid Sphere Pyramid Cone Cylinder

 7.2 Bentuk Dua Dimensi
• 2D is a shape that has one flat surface and not thick.

 Example of 2D Shape Square Rectangle Triangle Circle

 7.3 Penyelesaian masalah

Farid draws a rectangular shape. He calculates the number of vertices that the same square has.

How many corners will Farid draw?

The corners of a rectangle are marked with black arrows in the picture above.

So, there are four black arrows that mean a rectangle either four corners.

So the correct answer is the four corners that Farid will draw.
