Saudi Arabia has proven oil reserves of
2.63 1011 barrels. Kuwait has proven
oil reserves of 9.78 1010 barrels.
Canada has proven oil reserves of
1.789 1011 barrels. What are the
combined proven oil reserves of the
three countries?
2.63*10^11
0.978*10^11
1.789*10^11
--------------
5.397*10^11
To find the combined proven oil reserves of the three countries (Saudi Arabia, Kuwait, and Canada), you need to add up their respective proven oil reserves.
The proven oil reserves of Saudi Arabia are given as 2.63 × 10^11 barrels.
The proven oil reserves of Kuwait are given as 9.78 × 10^10 barrels.
The proven oil reserves of Canada are given as 1.789 × 10^11 barrels.
To get the combined proven oil reserves, you simply add these three values together:
2.63 × 10^11 + 9.78 × 10^10 + 1.789 × 10^11
Using standard arithmetic, you can add up these values:
= 2.63 × 10^11 + 9.78 × 10^10 + 1.789 × 10^11
= (2.63 + 1.789) × 10^11 + 9.78 × 10^10
= 4.419 × 10^11 + 9.78 × 10^10
= 5.397 × 10^11 barrels
Therefore, the combined proven oil reserves of the three countries is approximately 5.397 × 10^11 barrels.
