Question

A cube-shaped box has side lengths of 1.5 m, and it exerts a force of 63 N on the ground. Calculate the pressure, in N/m², that the box exerts on the ground. If your answer is a decimal, give it to 1 d.p.​

Answer 1

28 N/m²

Explanation:

Since you are calculating pressure, you want your question in N/m².

Note that the one side of the box has a length of 1.5m, and so to get the area of the bottom face, you need to square 1.5m::

(1.5m)² = 2.25m²

Then you need to use the formula P=F/A

Where P is pressure, F is force, and A is area, plug in your variables::

P =
`(63N)/(2.25m^(2) )`

Then you get an answer of:
`28 (N)/(m^(2) )`

You always want to make sure that the answer's units align with what you are told to solve for. In this case, they do, so no further steps are needed.

Hope this helps! :)
