Explanation

Let V1​ and V2​ be two volume of cubes.

l1​ and l2​ be edges of the two cubes.

We know that,

Volume of cube V=l3

So,

⇒  V2​V1​​=l23​l13​​

⇒  18​=(l2​l1​​)3             [ Given ]

∴  l2​l1​​=12​

∴  Ratio of their edges is 2:1.

Explanation

According to Boyle's Law, for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume

. This means that if you decrease the volume, the pressure will increase, and vice versa.

Mathematically, it is expressed as: P1V1 =P 2​ V2  where  P is the pressure, and V is the volume.

Therefore, if the volume decreases, the pressure will increase.
