Answer 1

Answer :

• 600 persons can sit in a cinema hall.

Given :

• The dimensions of a cinema hall are 100m , 50m and 18m

To find :

• How many persons can sit in a cinema hall of each persons require 150m³

Solution :

Here,

• Length is 100m
• Breadth is 50m
• Height is 18m

We know that, Formula of volume of cuboid,

• Volume of cuboid = lbh

Where , l is length, b is breadth and h is height

》Volume of cuboid = length × breadth × height

》100 × 50 × 18

》90000 m³

Hence , Volume of cinema hall is 90000m³.

Now Given that, each persons require 150 cubic metre then,

• Number of people can sit in a cinema hall = Volume of cinema hall/required person

》90000/150

》600

Hence , 600 persons can sit in a cinema hall.
