Explanation
## Step 1:The problem provides the formula for pressure which is given as:###
The force exerted by the box on the table is given as 27 newtons and the pressure on the table due to the box is 30 newtons/m². We are asked to find the width of the box,
.## Step 2:We can rearrange the formula for pressure to solve for area. The rearranged formula is:###
Substituting the given values into the formula, we get:###
## Step 3:The area of the face of the box in contact with the table is given by the product of its length and width (1.2m and
respectively). Therefore, we can set up the equation:###
Solving for
, we get:###
