A river discharges 4 × 106 cubic feet of water into the Pacific Ocean each second. There are 86,400 seconds in one day. To find the amount of water discharged each day, a scientist multiplied 4 × 106 by 86,400 on his calculator. The display showed:

Answer:

Total volume of the water discharged by the river into the Pacific daily.

Step-by-step explanation:

3.456E + 14 represents the volume of the water discharged daily into the Pacific.  That should be written with units:  3.456E + 14 cubic feet

Answer:

[tex]3.456 \times 10^{11}ft^{3}[/tex] means the amount of water discharged each day.

Step-by-step explanation:

Givens

  • A rive discharges at a rate of [tex]4 \times 10^{6} ft^{3}/sec[/tex].
  • One day has 86,400 seconds.

Now, to find the amount of water discharged each day, we just need to multiply

[tex]4 \times 10^{6} ft^{3}/sec \times 86,400 sec=345,600 \times 10^{6} ft^{3}=3.456 \times 10^{6+5}=3.456 \times 10^{11}ft^{3}[/tex]

Actually, the number 3.456E + 14 doesn't mean anything here exactly, because the result is [tex]3.456 \times 10^{11}ft^{3}[/tex], that is, this is the right amount of water discharged each day, that's what actually means such number.
