Acube with edges exactly 2 cm long is made of material with a bulk modulus of 3.5 x 109 n/m2. when it is subjected to a pressure of 3.0 x 105 pa its volume is:

As we know by the formula of bulk modulus

now we can rearrange it as

now the final volume after pressure is applied is given as

now we know that

now plug in all data

so volume is above after pressure is applied over it
