To find the volume required to transport the 75 boxes, we first need to calculate the volume of one cube using the formula for the volume of a cube:
\[ V = s^3 \]
where \(s\) is the side length of the cube. In this case, the side length \(s\) is 18 inches.
Calculating the volume of one box:
\[ V = 18^3 = 18 \times 18 \times 18 = 5,832 \text{ in}^3 \]
Next, we need to calculate the total volume for 75 boxes:
\[ \text{Total Volume} = 75 \times 5,832 \text{ in}^3 \]
Now we calculate it:
\[ 75 \times 5,832 = 437,400 \text{ in}^3 \]
So, the total volume needed to transport the boxes is \(437,400 \text{ in}^3\).
Therefore, the answer is:
A) 437,400 in³
