${1.2 m}^{3}$ $"1.2 m"^3$

Explanation:

$P \cdot V = n \cdot R \cdot T$ $P*V=n*R*T " "$ (Ideal gas law)

Assuming that the amount of gas and the temperature are fixed, the product of the pressure and volume is constant at any given moment. Using this, you can find the simple equation:

For $P_{1}$ $P_1$ and $V_{1}$ $V_1$ as the initial pressure and volume and $P_{2}$ $P_2$ and $V_{2}$ $V_2$ as the pressure and volume at any given moment.

$P_{1} \times V_{1} = P_{2} \times V_{2}$ $P_1 xx V_1 = P_2 xx V_2$

Writing the values, we get:

${3 m}^{3} \times 200 kPa = V_{2} \times 500 kPa$ $"3 m"^3 xx "200 kPa" = V_2 xx "500 kPa"$

So

${600 kPa m}^{3} = V_{2} \times 500 kPa$ $"600 kPa m"^3 = V_2 xx "500 kPa"$

$V_2 = "600 kPa m"^3/"500 kPa" = 6/5 quad "m"^3 = "1.2 m"^3$

Since we only played with numbers, the volume is still as cubic meters.
