Question

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)

Answer 1

Answer: $2.14(10)^{16} m^{3}$

Explanation:

Assuming the cuboid has the following dimensions:

Width (W): $1.9(10)^{7} m$

Length (L): $1.9(10)^{7} m$

Height (H): $3700 m$

Its volume is: $V=(W)(L)(H)$

$V=(1.9(10)^{7} m)(1.9(10)^{7} m)(3700m)$

$V=1.34(10)^{18}m^{3}$

Now, if we want to know what is the $1.6 \%$ of this volume, we have to do the following:

$V=1.34(10)^{18}m^{3} \frac{1.6}{100}=2.14(10)^{16} m^{3}$ This is the 1.6 % of the volume of the cuboid
