How is it calculated?
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 , therefore the total surface area is .
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 .
Hope that made sense.
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
