Question

a room is 10 m× 8 m wide . If one packing case requires 20 cm × 40 cm of space, find the number of cases that can be exactly fitted on the floor. ​

Answer 1

Answer:

Step-by-step explanation:

Area of the room = 10m x 8m

= 80 sqm

Area of package case rwquired = 20 cm x 40cm

=800 sq.cm

=800 / 10000 sq.m

= 0.08 sq.m

Number of cases that can be exactly fitted on the floor = 80 / 0.08

=8000 / 8

=1000

Answer 2

Solution:-

Given:-

A room is 10 m× 8 m wide.

One packing case requires 20 cm × 40 cm of space.

To Find:-

The number of cases that can be exactly fitted on the floor.

Find:-

Area of Room = 10m × 8m

=) Area = 80 m²

Now,

Area for 1 packing Case = 20cm × 40cm

=) Area = 800 cm²

Converting cm² into m².

=) Area = 800/10000 m²

=) Area = 0.08 m²

Let "x" be the Number of cases that can be exactly fitted on the floor.

=) (x) × Area of 1 Case = Area of Room

=) (x) × 0.08 = 80

=) x = 80/0.08

=) x = 1000

Hence,

1000 cases can be exactly fitted on the floor.
