Determine the appropriate pad dimensions $($Length x Height$)$ for summer ventilation at $1$ air change per minute, for a gutter$-$connected greenhouse with total volume of $43,200$ m$3$if it uses corrugated cellulose of $150$ mm thickness with a face velocity of $1\mathrm{.}75$ m$/$s$.$ The length and height of the greenhouse is $300$ m and $2\mathrm{.}4$ m$,$ respectively.
