Solution
\[\text { Suppose that the breadth of the box is b cm }. \]
\[\text { Volume of the cuboidal box = 48 } {cm}^3 \]
\[\text { Height of the box }= 3 cm \]
\[\text { Length of the box }= 4 cm\]
\[\text { Now, volume of box = length }\times \text { breadth } \times \text { height }\]
\[ \Rightarrow 48 = 4 \times b \times 3\]
\[ \Rightarrow 48 = 12 \times b\]
\[ \Rightarrow b = \frac{48}{12} = 4 cm\]
\[ \therefore \text { The breadth of the cuboidal box is 4 cm } .\]
