Assume that the side length of the cube is m.
Since all sides of the cube are equal, therefore, the volume of the cube can be measured using the following rule:
volume of cube = m^3

Substitute in this equation with the length given:
volume = (4.33)^3 = 81.1827 cm^3

From the standards of units conversions, 1 cm^3 = 0.001 liters
Therefore:
volume of cube = 81.1827 cm^3 = 0.0811827 liters

Answer from: steven122048i

The volume of the required cube is $81.182 \texttt{ cm}^3$

Explanation:

The edge of the cube is $a=4.33\texttt{ cm}$ .

Cube is three dimensional figure with all sides equal.

Now, it is required to calculated the volume of the cube.

The volume of a cube can be calculated as,

$V=a^3\\V=(4.33)^3\\V=81.182 \texttt{ cm}^3$

Therefore, the volume of the required cube is is $81.182 \texttt{ cm}^3$ .

passing a magnet thought the

mixture , because iron gets attracted to magnet .

Answer from: Quest

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the
