Answer:
1) 
2) 16 m
Explanation:
1)
The hole in the ground has the shape of a prism, so its volume can be calculated as the volume of a prism:
where:
l is the length
w is the width
h is the height of the prism
For the hole in this problem, we have:
l = 5 m (length)
w = 3 m (width)
h = 6 m (height)
Therefore, the volume of the hole (and of earth removed) is
2)
The base of the room in this problem has the shape of a rectangle, so we can write its area s
where:
l is the length
w is the width (breadth)
For the room in this problem, we have:
is the area of the base of the room
w = 6 m (breadth)
Therefore, the length of the room can be found by re-arranging the equation:
It means, it can't exist in the US.
<span>Mainly because the Constitution is the supreme law the US and anything that goes against any amendment in the Constitution is unconstitutional and therefore cannot exist as proposed.

Answer:
The correct option is letter A: Increased reflected sun energy of urban environments relative to that of natural landscapes
Explanation:
Option A is the perfect example of the result of urban heating and not a cause of it. The responsible is the man simply because we create urban environments that are not eco-friendly and this increases the reflected solar energy, therefore increases the heat. So, again, the increase of the heat would be the result.
Answer:
- Chemical factors;
The chemical factors like the salinity and the composition are very important for the formation of the soil, as well as for determining the type of soil.
- Physical factors;
The most important of the physical factors are the erosion and deposition. While the erosion removes layers of soil from a certain places, the deposition brings that material on another place and makes layers which set of a new start for soil formation on another place.
- Climatic factors;
The climate is extremely important because it sets the basic for the soil formation. Different types of climate result in different types of soil, and the fact that the climate is the factor that enables certain plants to grow in certain conditions, makes it possible for the soil to become richer or poorer depending on the biomass available.
