To find the volume of a rectangular prism, we can use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions of the prism:
- Width = 6 cm
- Length = 2.5 cm
- Height = 4.5 cm
Now we can substitute in the values:
\[ \text{Volume} = 2.5 , \text{cm} \times 6 , \text{cm} \times 4.5 , \text{cm} \]
First, we compute \( 2.5 \times 6 \):
\[ 2.5 \times 6 = 15 \]
Next, we compute \( 15 \times 4.5 \):
\[ 15 \times 4.5 = 67.5 \]
Now, we have the volume in cubic centimeters:
\[ \text{Volume} = 67.5 , \text{cm}^3 \]
To express this as a mixed number in simplest form, we can break down \( 67.5 \) into a whole number and a fractional part.
The whole number is \( 67 \) and the fractional part \( 0.5 \) can be expressed as \( \frac{1}{2} \). Therefore:
\[ 67.5 = 67 \frac{1}{2} \]
Thus, the volume of the prism is:
\[ \boxed{67 \frac{1}{2}} , \text{cm}^3 \]
