A hydraulic jump occurs in a $1.0 \mathrm{~m}$ wide horizontal, frictionless, rectangular channel, with a pre-jump depth of $0.2 \mathrm{~m}$ and a post-jump depth of $1.0 \mathrm{~m}$. The value of $g$ may be taken as $10 \mathrm{~m} / \mathrm{s}^2$. The values of the specific force at the pre-jump and post-jump sections are same and are equal to (in $\mathrm{m}^3$, rounded off to two decimal places)_______________.
