Question

The base of a box is .45 m by .65 m. It weighs 8694 N. What is the pressure exerted on the floor by the box?

Answer 1

`Pressure = 29723.1\ N/m^2`

Step-by-step explanation:

Given

`Force = 8694N`

`Length = 0.45m`

`Width = 0.65m`

Required

The force exerted on the floor by the box

First, calculate the area covered by the box (i.e. the base area)

`Base\ Area = Length * Width`

`Base\ Area = 0.45m * 0.65m`

`Base\ Area = 0.2925m^2`

Pressure is calculated as:

`Pressure = (Force)/(Area)`

`Pressure = (8694N)/(0.2925m^2)`

`Pressure = 29723.0769231\ N/m^2`

`Pressure = 29723.1\ N/m^2` --- approximated
