To find the width of the cabinet using the volume formula, we start with the formula for the volume of a rectangular prism:
\[ V = L \times W \times H \]
Where:
- \( V \) = volume
- \( L \) = length
- \( W \) = width
- \( H \) = height
In this case:
- The volume \( V = 60 , \text{ft}^3 \)
- The height \( H = 5 , \text{ft} \)
- The width \( W \) is what we want to find.
- The length \( L \) can be inferred as \( 4 , \text{ft} \) (the weight mentioned seems to be a typo; let's assume it refers to length).
Rearranging the volume formula to find width \( W \):
\[ W = \frac{V}{L \times H} \]
Next, we can plug the known values into this formula:
\[ W = \frac{60}{4 \times 5} \]
Calculate the product in the denominator:
\[ 4 \times 5 = 20 \]
Now, substituting this into the equation for width:
\[ W = \frac{60}{20} = 3 \]
So, the width of the cabinet is:
\[ \boxed{3 , \text{ft}} \]
This means the cabinet's dimensions are 4 feet in length, 3 feet in width, and 5 feet in height, making it suitable for the designated space in their home.
