Question

A cupboard stands on the floor whose base is square with sidelengths are 1.20 m. Together, the cupboard weighs 2450 N.What is the pressure the cupboard exerts on the floor in Pa?

Answer 1

Answer: 1701 Pa

Explanation:

The first step is to calculate the area of the base of the cupboard. From the information given,

length = 1.2

Area of square = length of side^2 = 1.2^2 = 1.44 m^2

Weight or force = 2450

The formula for calculating pressure is expressed as

Pressure = Force/area

Pressure = 2450/1.44

Pressure = 1701 Pa
