What would to the earth if it shrinks to 1/3 of a cubic inch. (It is possible)

Acube has a volume of 2011 cubic inches. what is the angle measure between a side of a cube and its interior diagonal?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
