Solution Steps

Step 1: Identify the dimensions of the original crate

The original crate has dimensions of \( 2.5 \, \text{ft} \), \( 2.5 \, \text{ft} \), and \( 4 \, \text{ft} \).

Step 2: Calculate the volume of the original crate

The volume \( V \) of a rectangular prism is given by: \[ V = \text{length} \times \text{width} \times \text{height} \] Substituting the given dimensions: \[ V = 2.5 \times 2.5 \times 4 = 25 \, \text{ft}^3 \]

Step 3: Apply the scale factor to find the volume of the new crate

The scale factor is \( 3 \). Since volume scales with the cube of the scale factor, the new volume \( V' \) is: \[ V' = V \times (\text{scale factor})^3 \] Substituting the values: \[ V' = 25 \times 3^3 = 25 \times 27 = 675 \, \text{ft}^3 \]

Final Answer

\(\boxed{675 \, \text{ft}^3}\)
