2. Outline
 Dimension
 Approximation
 Grammar

3.  Dimensions
 A mode of linear extension of which there are three in
space and two on a flat surface, which corresponds to one
of a set of coordinates specifying the position of a point.
 Includes :
 ( Length , Broad “wide” , Depth , Height and Time…)

4.  Dimensions
 Length: the distance from one end of something to the
other end.
 Depth: a distance below a surface.
 Height: rising or extending upward a great distance.

5.  Dimensions
 Dimensions are countable and have unit.
 Dimensions are used as either (noun) or (adj)
Dimension in the sentence:
 The height of the derrick is 60 meters. (noun)
 This room is five meters long. (adj)

6.  Dimensions
 Unit of Dimensions
 SI unit for dimensions is (meter, kilo meter…)
 US unit for dimensions (feet, mile…)

7.  Approximation
An approximation is anything that is similar but not exactly
equal to something else.
*Approximate and Approximately
 Includes:
(close “closely” , near “nearly” and almost …)

8.  Approximation
Using in sentence:
Approximations uses with Dimensions or any things that
approximate to another thing.
Using approximation (things to another thing):
 The car is stopped near (not “nearly”) bridge.
 The apartments are close (not “closely”) to each other

9.  Approximations
 Using with Dimension:
 The room is nearly (not “near”) 3 meters high.
 This road is approximately (not "approximate") 100 mile
long
 Approximation usually come with number of
dimensions

10.  Approximations
Why using approximations?
 When we speak, we often try not to be too exact
because it can sound very direct. As a result, we add
expressions to make what we say more approximate.

11.  Grammar
Dimension & Approximation
Noun:
The + dimensions + of the + something is + (approximation)
number
Adjective:
Subject + is + (approximation) number + measurement +
dimension

12.  Grammar
Asking about dimension (noun)
 What is the + dimension + of + something?
 Example (What is the depth of the well? )

13.  Grammar
Answering ( noun )
 The + dimension + of the + something + is + (approximately)
number + measurement
 Example ( The depth of the well is (approximately) 2000
meters. )

14.  Grammar
Asking about dimension ( adjective )
 How + dimension + is + something ?
 How high is the rig ?

15.  Grammar
Answering ( adjective )
 Subject + is + (approximately) number + measurement +
dimension
 The rig is (approximately) 25 meters high.

16.  Conclusion
 Dimension definition and Units
 What is approximation
 Why we use approximation
 Approximations & Dimension (grammatical rule)
