Given that

The length of the each side of a box

(a) = 7 cm

Since, all sides of the box are equal then it is a cubical box .

We know that

The volume of a cube whose side is 'a units' is "a³ cubic units".

Therefore,

The volume of the box = 7³ cm³

=> Volume = 7×7×7 cm³

Therefore, The volume = 343 cm³

The volume of the given box is 343 cm³
