Notes

Visualising Solid Objects:

Visualising solid shapesis a very useful skill. You should be able to see ‘hidden’ parts of the solid shape.

       

Suppose you form a cuboid by joining such cubes. You will be able to guess what the length, breadth, and height of the cuboid would be.

If two cubes of dimensions 2 cm by 2cm by 2cm are placed side by side, what would the dimensions of the resulting cuboid be?

Solution:
As you can see in the figure,
when kept side by side, the length is the only measurement which increases, it becomes 2 + 2 = 4 cm.
The breadth =2 cm and the height = 2 cm.
