Here is your answer.

Volume = L × B × H
$440 = 10 \times b \times 8 \\ \\ b = \frac{440}{10 \times 8} \\ \\ b = 5.5 \: cm$
Therefore B = 5.5 cm

Answer 2

Given:

Volume = 440 cm³

Length = 10 cm

Height = 8 cm

Requirements:

Breadth =  ??

Formula of a Volume to find out Breadth is given by,

Volume = Length * Breadth * Height  

440 = 10 * 8 * Breadth

Breadth = 440 / 80

Breadth  = 5.5 cm

So that the value of a  breadth is 5.5 cm
