Question

6) A box weighing 250 N is kept on the floor. What is the amount of pressure it is exerting on the floor if the length of the box is 50 cm and the width of the box is 25 cm?​

Answer 1

Given

• Weight = 250 N
• Area Covered by box = 50 cm × 25 cm

To Find

• Pressure = ?

Solution

✇ Formula Used :

• Pressure = Weight/Area
• Area(Rectangle) = Length × Breadth

✇ Pressure :

➳ ${\sf{ Pressure = Weight/Area }}$

➳ ${\sf{ Pressure = 240/L × B }}$

➳ ${\sf{ Pressure = 240/50 × 25 }}$

➳ ${\sf{ Pressure = 240/1250 }}$

➳ ${\sf{ Pressure = 240/1.250 }}$

➳ ${\red{\sf{ Pressure = 192 \; Pa }}}$

✇ Therefore :

Pressure on the box is 192 Pascal .

Additional Info. :

• 1 m = 100 cm

• Pressure = Weight/Area or
• Pressure = Force/Area
