To determine how many cubic feet of dirt Victor needs to fill his garden box completely, follow these steps:
1. Identify the dimensions of the garden box:
- Length: 3½ feet (which can also be written as 3.5 feet)
- Width: 4 feet
- Depth: 1 foot
2. Understand the formula for calculating the volume of a rectangular prism (which is the shape of the garden box):
[tex]\[
\text{Volume} = \text{Length} \times \text{Width} \times \text{Depth}
\][/tex]
3. Substitute the given dimensions into the formula:
[tex]\[
\text{Volume} = 3.5 \text{ feet} \times 4 \text{ feet} \times 1 \text{ foot}
\][/tex]
4. Perform the multiplication:
[tex]\[
3.5 \times 4 = 14.0
\][/tex]
Thus, the garden box requires 14.0 cubic feet of dirt to fill it completely. Therefore, the correct answer is:
B. 14
