A black hole is a cosmological object that is created when a massive star comes to the end of its life and collapses under its own gravity. Black holes have massive gravitational fields that even light cannot escape beyond a certain distance. Before being engulfed, matter that is pulled into a black hole should become very hot and emit electromagnetic radiation.

1 pound (lb) = 453.592 g
Therefore, 5.4 pounds will be equivalent to 5.4 × 453.592 = 2449.397 g
1 cubic inch = 16.387 cubic cm
Therefore, 13.6 cubic inches will be equivalent to 13.6 × 16.387 = 222.863 cm³
Density is given by mass divided by volume
Thus density = 2449.397 g / 222.863 cm³
= 10.991 g/cm³
Answer:
Energy storage plays an important role in this balancing act and helps to create a more flexible and reliable grid system. For example, when there is more supply than demand, such as during the night when low-cost power plants continue to operate, the excess electricity generation can be used to power storage devices.
