Read and answer the questions on each slide. To move through the tutorial, press the return key or the right arrow key. To return to a previous slide, press the left arrow key. Make sure to use your headphones, so you won’t disturb others. Feel free to view the tutorial more than once if you have any questions. After finishing the tutorial, report to Mr. Tauke for a quick review of surface area concepts.

How much cardboard in a cardboard box?

Do you see the RED face? What are the dimensions of this rectangle? 10 in. 4 in.

Do you see another face that is just like the RED face? Where is it located?

Yes, it ’ s on the back. 10 in. 4 in. 10 in. 4 in.

Now there are 2 rectangles 40 in 2 that each have an area of 40 sq. in.

Do you see the BLUE face? What are the dimensions of this rectangle? 4 in. 7 in.

Do you see another face that is just like the BLUE face? Where is it located?

Yes, it ’ s on the left side. 4 in. 7 in. 4 in.

Now there are 2 rectangles that each have an area of 28 sq. in. 28 in 2

Do you see the GREEN face? What are the dimensions of this rectangle? 10 in. 7 in.

Do you see another face that is just like the GREEN face? Where is it located?

Yes, it ’ s on the bottom. 10 in. 7 in. 10 in. 7 in.

Now there are 2 rectangles that each have an area of 70 sq. in. 70 in 2

Now we just need to add all the areas of the sides together. + + + + 70 in 2 28 in 2 40 in 2 28 in 2 70 in 2

A common mistake is to add the dimensions of the prism together, and not the areas of the faces. Make sure to avoid this mistake. + + + + 10 in 2 7 in 2 4 in 2 7 in 2 10 in 2

The total Surface Area for this rectangular prism is 40 + 40 + 28 + 28 + 70 + 70 = 276 in 2
