Surface area of 3-dimensional shapes

In this section, we will learn how to calculate the surface area of 3D objects. We will also look further into the subject ? What would happen to the surface area if the shapes are cut into pieces? How about a piece is cut out of the shape?

Lessons

    • a)
      What are the dimensions of the cutout piece?
    • b)
      How does the surface area of the original rectangular object change after cutting out the corner piece?
  • 2.
    Below is a rectangular object formed by six blocks which all have the same size.
