Hello guys, it's Jaypee. We started the class with another mental math quiz and continue to begin with our unit about Geometry. We also did some work & Mr. P explained some of the key terms about Surface area of Prisms on the booklet.


These are the key terms :

• Surface area is the area required to cover a 3D shape. It is measured in square units.
• Volume is the amount of space occupied by a 3D object. It is measured in cubic units.

Surface area represents the area of all faces of an object, and can be defined in two ways:

      Lateral Surface Area

• Pyramids: Area of all faces (triangles) except the base.
• Prisms: Area of all faces (rectangles) expect the ends.

      Total Surface Area

• Area of all faces including the ends or base.                                                                                

 (Note: A special case, which will be dealt with is the surface areas of spheres.)

A prism is a 3D object that has two identical ends and all flat sides.


Mr. P also gave us a work sheet about "Sketching Nets of Solids".

We also did the Example 2 on the booklet. This might help you understand how we did it.

I also found a good tutorial video about the Surface Area of Prisms. This also might help you to understand the lesson. To watch please Click here

In addition to this, Here are some of the basic formulas that might help you as we walk throughout this unit.
