To solve the problem related to constructing a box from a square piece of cardboard by cutting out squares of side length \( x \) from each corner, we will complete parts (a) through (e) step by step.

### **Part 1** (a)
**Write an expression for the height of the box that is constructed.**

The height of the box is equal to the side length of the square that is cut out:
\[
\text{Height of the box} = x \text{ inches}
\]

### **Part 2** (b)
**Write an expression for the dimensions of the base of the box that is constructed.**

If the original piece of cardboard is \( 38 \) inches on each side, cutting out squares of side \( x \) on each corner will reduce both the length and width of the base by \( 2x \) (since squares are cut from both sides):

\[
\text{Length of the base} = 38 - 2x \text{ inches}
\]
\[
\text{Width of the base} = 38 - 2x \text{ inches}
\]

So, the dimensions of the base of the constructed box are:
\[
(38 - 2x) \text{ inches by } (38 - 2x) \text{ inches}
\]

### **Part 3** (c)
**Use the formula \( V = lwh \) to find an equation that represents the volume of the box.**

Substituting the expressions for length, width, and height into the volume formula:
\[
V = (38 - 2x)(38 - 2x)(x)
\]
Simplifying:
\[
V = (38 - 2x)^2 \cdot x
\]
Thus, the volume of the box is:
\[
V = x(38 - 2x)^2
\]

### **Part 4** (d)
**Use the equation of the volume of the box to find the values of \( x \) that make \( V = 0 \).**

To solve \( V = 0 \):
\[
x(38 - 2x)^2 = 0
\]
This gives us two conditions:
1. \( x = 0 \)
2. \( (38 - 2x)^2 = 0 \) → \( 38 - 2x = 0 \) → \( 2x = 38 \) → \( x = 19 \)

So the values of \( x \) that make \( V = 0 \) are:
\[
x = 0, 19
\]

### **Part 5** (e)
**For which of these values of \( x \) does a box exist if squares of length \( x \) are cut out and the tabs folded up?**

- \( x = 0 \): Here the height is \( 0 \), thus a box does not exist.
- \( x = 19 \): Cutting out squares of this size means the base dimensions will be \( 38 - 2(19) = 0 \), which means no box can exist either.

Since for both values of \( x \), the volume ends up being zero or not creating a valid box, the correct answer is:
\[
\text{A. For neither of the values of } x.
\]

### **Final Summary**
- **(a)** Height: \( x \)
- **(b)** Dimensions of base: \( (38 - 2x) \text{ inches by } (38 - 2x) \text{ inches} \)
- **(c)** Volume: \( V = x(38 - 2x)^2 \)
- **(d)** Values of \( x \) for \( V = 0 \): \( 0, 19 \)
- **(e)** Box existence: \( A. \text{ For neither of the values of } x. \)
