To find the width of the box, we can use the formula for the volume of a right rectangular prism:

\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]

We are given the following information:

  • Volume = 162,000 cubic centimeters
  • Height = 40 cm
  • Length = 90 cm

We can rearrange the formula to find the width:

\[ \text{width} = \frac{\text{Volume}}{\text{length} \times \text{height}} \]

Substituting in the known values:

\[ \text{width} = \frac{162,000 , \text{cm}^3}{90 , \text{cm} \times 40 , \text{cm}} \]

Calculating the denominator:

\[ 90 , \text{cm} \times 40 , \text{cm} = 3600 , \text{cm}^2 \]

Now we can calculate the width:

\[ \text{width} = \frac{162,000 , \text{cm}^3}{3600 , \text{cm}^2} \]

Calculating this gives:

\[ \text{width} = 45 , \text{cm} \]

So, the width of the box is 45 cm.
