$\sf\large{\red{\underline{\blue{\underline{Question:-}}}}}$

the dimensions of cinema hall are 100m , 50m and 18m . how many person can sit in the hall . of each person require 150 cubic .cm of air.

$\sf\large{\red{\underline{\blue{\underline{Given:-}}}}}$

• $\sf Length=100m , width = 50m\: and\: height=18m$
• $\sf Volume\:of\:air\: required\:each\:person=150cm^3$

$\sf\large{\red{\underline{\blue{\underline{To\:Find:-}}}}}$

• $\sf How:many\:person\:can\:sit\:in\: the\:hall=?$

$\sf\large{\red{\underline{\blue{\underline{Solution:-}}}}}$

$\sf →Volume\:of\:hall=L+B×H \\\sf →Volume\:of\:hall=100×50×18$

$\sf→ No.\:of\:person=\frac{Volume\:of\:hall}{Volume\:of\:air\: required\:each\:person}\\\sf→ No.\:of\: person= \frac{100×50×18}{150}\\\sf→ No.\:of\:person 100×6\\\sf→ No.\:of\:person=600$
