Here, p=10 atm = 10\times 1.013\times 10^{5}Pa 

\text { Buck modulus for glass slab }=37 \times 10^9 \mathrm{Nm}^{-2}

\text { using the relation } B=\frac{P}{\Delta V / V} \text {, we get }

\frac{\Delta V}{V}=\frac{P}{B}

\begin{aligned} & =\frac{10 \times 1.013 \times 10^5}{37 \times 10^9} \\ & =\frac{1.013}{37 \times 10^3} \\ & =0.0274 \times 10^{-3} \end{aligned}
