At which period do the principal energy levels begin to overlap in energy content?
Notice on the periodic table that 4s comes before the 3d. That is the first place where energy overlap.
Why does the 4S orbital begin to fill before the 3D orbital?
Electrons occupy orbitals in a definite sequence, filling orbitals with lower energies first. Generally, orbitals in a lower energy level have lower energies than those in a higher energy level. But, in the third level the energy ranges of the principal energy levels begin to overlap. As a result, the 4s sublevel is lower in energy than the 3d sublevel, so it fills first.

How many MMBTU is equivalent to Normal cubic meters?
The "BTU" is a unit of energy. The "MMBTU" is a million of them ... still a quantity of energy. The "cubic meter" is a unit of volume. If the substance filling the volume is named ... and its pressure also specified in the case of a gas ... then it's possible to begin calculating the quantity of energy available when the substance is burned.
