Answers
The elevator can accommodate 30 people
Step-by-step explanation:
Dimensions of the elevator = 2.5 m long, 1.5 m broad and 2.2 m high.
We can ignore the height with regard to the number of people it can accommodate.
Area of the elevator = length * breadth = 2.5 * 1.5 = 3.75 square meters.
Number of people per square meter = 8
Number of people in the elevator = 3.75 * 8 = 30
Option A is the answer.
The elevator can accommodate 30 people.
Step-by-step explanation:
Hello Dear,
On 1 square meter carpet , total people stand= 8
So, at the elevator= area of elevetor × 8
= (2.5×1.5) ×8
= 30 people can stand.
( here we ignor the height of elevetor ,because standing capability of people depends on surface area ,not on its volume)
I hope you understand it, thanking you.
