can you help me with math I don't understand that.

Question

The average ocean depth is 3.7 × 103 m, and the area of the oceans is 3.6 × 1014 m2. What is the total volume of the ocean in liters? (One cubic meter contains 1000 liters. Round your answer to one decimal place.)

 

 

-------× 10 ------L

Answer 1

We can find the total volume by multiplying the average area by the average depth. We get:

V=(3.6x10¹⁴)(3.7x10³)=13.32x10¹⁷ m³

 

Now we can convert m³ to liters using the conversion factor (1m³/1000L):

13.32x10¹⁷ m³(1000L/1m³)=13.32x10²⁰ L or 1.3x10²¹L

Answer 2

Volume = length x width x depth

 

           = (length x width) x depth

 

           = area x depth

 

          = 3.6 x 10^14 square meters x  3.7 x 10^3 meter

 

         = 13.32 x 10^17 cubic meters

 

         = 1.332 x 10^18 cubic meters

 

 

I cubic meter is 1000 liters.                1000 liters

So 1.332 x 10^18 cubic meters x ------------------------

                                                      1 cubic meter

 

1.332 x 10^18 x 1000 liters

 

= 1.332 x 10^18 x 10^3 liters

 

= 1.332 x 10^21 liters
