What is "TSA"? If you're referring to "total surface area", the methods involved will vary with the information provided.

3. ## TSA

Yes, I was referring to the Total Surface Area of a cube. What's the difference between that and the volume? For example if a cube is 10 cm, how are the volume and the TSA calculated?

The Total Surface Area of a shape is the area of its "outer wrapping". This area is measured in squares.

The Volume of a shape is how much "stuff" you can fit inside it. This "stuff" is measured in cubes.

Notice that a cube has 6 faces.

If a cube is 10cm in length (?) then...

The area of one face is $\displaystyle 10^2\textrm{cm}^2 = 100\textrm{cm}^2$, therefore the total surface area is $\displaystyle 6\times 100\textrm{cm}^2 = 600\textrm{cm}^2$.

Since ten centimetre squares can fit along the length and ten centimetre squares can fit along the width, and ten layers can be stacked, the volume is $\displaystyle 10^3\textrm{cm}^3 = 1000\textrm{cm}^3$.

Hope that made sense.

5. ## Clarification

So, if I understood correctly, the 100 cm2 is the length x the width. Now: if a cube is 6cm in length, 4cm in width and 5 cm in height, how woukl I calculate the surface area (volume is l x w x h). Are the surface area and the total surface area the same thing? Thanks for your help

TSA = 2[(6)(4) + (6)(5) + (4)(5)] cm^2.

I have a feeling that TSA and your understanding of surface area are the same thing.
