Solution Steps

Step 1: Calculate the Volume of the Box

The volume \( V \) of a rectangular box is given by the product of its length \( l \), width \( w \), and height \( h \).

Given:

  • Length \( l = 18 \) inches
  • Width \( w = 14 \) inches
  • Height \( h = 7 \) inches

\[ V = l \times w \times h \] \[ V = 18 \times 14 \times 7 \] \[ V = 1764 \text{ cubic inches} \]

Step 2: Represent the Length of the New Box in Terms of \( x \)

Suppose each dimension is increased by \( x \) inches. The new length \( l' \) of the box is:

\[ l' = 18 + x \]

Step 3: Represent the Width of the New Box in Terms of \( x \)

The new width \( w' \) of the box is:

\[ w' = 14 + x \]

Final Answer

  1. The volume of the box is \( 1764 \) cubic inches.
  2. The length of the new box in terms of \( x \) is \( 18 + x \).
  3. The width of the new box in terms of \( x \) is \( 14 + x \).
