Question

QUESTION 8 The volume of water held by the 2 main ice caps (Antarctica and Greenland) is about 1.6 % the volume of the ocean. What is 1.6 % of the cuboid's volume (problem 3) in cubic meters? (Use scientific notation and keep 3 significant figures, eg. 1.00E10) QUESTION 9 suppose the cuboid's sides cannot change, only the depth. How much must the cuboid's water level rise to accommodate the new volume in meters? 1 6% of the depth (round to closest integer, eg 1) QUESTION 10 What fraction of the ice sheets (wrt total amount of ice sheets) would need to melt to result in a 1 meter sea level rise? hints: You get the amount of sea level rise (in meters) from melting the whole ice burg (let's say 1 unit of ice burg) in question 9, so if the sea level rise is 1 meter, how many units of ice burg is melted? (Use scientific notation and keep 2 significant figures, eg. 1.0E10)

Explanation / Answer

According to the chegg rule if multiple questions are posted it is better to answer first full question, so maintaining the rule set by chegg i will be answering the 8th question complete. If you have any queries or doubt please leave a comment and i will reply asap.

According to the information provided by
1. "Antarctica" World Book Encyclopedia. Chicago: World Book, 1999:532, it says Antarctica has volume of 7¼ million cubic miles i.e, 30 million km3 representing about 70% of the world's fresh water.
2. "Greenland" World Book Encyclopedia. Chicago: World Book, 1999:325, it says it covers around 1,740,500 km2. The ice caps is over 1 mile (1.6 km) thick and thickness of over 2 miles (3.2 km) has been measured.

So the standard result says,
total volume of Antarctica = 30 x 106 km3
total volume of Greenland = 2.8 x 106 km3
-----------------------------------------------------
total volume = 32.8 x 106 km3

The question states 1.6% of total volume of Antarctica and greenland ocean which is equal to =>
1.6% of 32.8 x 106 km3 = 1.6/100 x (32.8 x 106)
= 524.8 x 103 km3  

Therefore, 1.6% of cuboid volume in cubic meter is 524.8 x 106 m3.
