I really need help to solve these complex issues (25 points) SITUATION 1: A construction company is building a 12-storey building, with 4 apartments equal to the floor plan per floor, in a prime area of ​​a city, at a sale price of R $ 4,000.00 / m². The engineer “Piter” is responsible for this work and needs, among other duties, to carry out the survey of materials and their respective prices for the execution of the work. As there are many necessary materials, Piter asked his “master of works”, Mr. “Eliot”, to help him in calculating the quantity needed for the acquisition of the floors, as well as the necessary values ​​for this purchase, according to the specifics below :

Given the above, determine, showing in detail the calculations, what is required:
- the number of whole boxes of each type of floor required that must be purchased for all apartments, taking into account the 10% prevention margin, as well as the total value of that floor purchase.
- the value of an apartment, taking into account the square meter value of sale mentioned above.

SITUATION 2: The Piter engineer needs to calculate the size (dimensions) of the water tank and the amount of liters of water needed to supply the building in question. For this, it will take into account the following engineering data:
1) for the purposes of “population” to be served, two people are calculated for each double room and one person for each single room;
2) it is estimated that each person spends 200 liters of water per day;
3) a quantity of 15,000 liters of water should be reserved for fire emergencies.
4) two reservoirs should be built to store all the water, one in the basement to hold 40% of the total water and the other in the roof to accommodate the rest.
Taking into account the data above, determine:
- the amount of water, in cubic meters, that must be reserved for this building;
- being the water tanks of the building in the shape of a prism (cube), determine approximately the minimum dimensions (length, width and height) required of each reservoir (subsoil and roof) to accommodate the total amount of water in the building building.
