Units of Measurement of Length

1) Convert the Angelfish Drive Depth Into Centimeters.

Angelfish can drive at a depth of 4500 m.
We know, 1 m = 100 cm.
Now, 4500 m = (4500 × 100) cm = 450000 cm.
So, the required answer is 450000 cm.

2) Fill In The Blanks:

ans: 

3) Represent the Scuba Diver’s Depth in Millimeters.

Scuba Diver can dive at a depth of 20 m – 40 m.

We know that 1 m = 1000 mm
Then, 20 m = (20 × 1000) mm = 20000 mm
40 m = (40 × 1000) mm = 40000 mm
Scuba Divers can drive at a depth of 20000 mm – 40000 mm.

4) Represent the Twilight Zone in Centimeters.

The length of the Twilight Zone is 200 m to 1000 m

We know that 1 m = 100 cm
200 m = (200 × 100) cm = 20000 cm
1000 m = (1000 × 100) m = 100000 m
The length of the Twilight Zone is 20000 cm to 100000 cm.

5) Blue Whale Can Drive at the Depth

i) 5km ii) 50mm
iii) 50000cm iv) 5000m

Blue whales can drive at a depth of 500m.
We know that 1 m = 100 cm
So, 500 m = (500 × 100) cm = 50000 cm
The correction is option iii) 50000 cm.

6) Find the Length of the Midnight Zone in kilometres (km).

The length of the Midline Zone is 1000 m to 4000 m.
We know that 1000 m = 1 km
Then, 4000 m = (4 × 1000) m = 4 km
So, the midline zone is 1 km to 4 km.

7) Which Zone Contained the Largest Length?

The length of the Epipelagic Zones is
= (200 – 0) m
= 200 m
The length of the Mesopelagic Zone is
= (1000 – 200) m
= 800 m
The length of the Bathypelagic Zone is
= (4000 – 1000) m
= 3000 m
The length of the Abyssopelagic Zone is
= (6000 – 4000) m
= 2000 m
The length of the Hadal Zone is
= (11000 – 6000) m
= 5000 m
So, the zone with the longest length is Hadal Zone.
