Solution

\[\text { Suppose that the breadth of the box is b cm  }. \]

\[\text { Volume of the cuboidal box = 48 } {cm}^3 \]

\[\text { Height of the box  }= 3 cm \]

\[\text { Length of the box  }= 4 cm\]

\[\text { Now, volume of box = length  }\times \text { breadth } \times \text { height }\]

\[ \Rightarrow 48 = 4 \times b \times 3\]

\[ \Rightarrow 48 = 12 \times b\]

\[ \Rightarrow b = \frac{48}{12} = 4 cm\]

\[ \therefore \text { The breadth of the cuboidal box is 4 cm } .\]
