✺ Given :

• Area of the face GHEF = $\dfrac{25}{4}$ unit²
• breadth (b) = $\dfrac{8}{5}$ unit

✺ To Find :

• Volume of the Cuboid = ?

✺ Explanation :

Here the face GHEF will treat as The base face of area $\dfrac{25}{4}$ unit² , and the breadth (b) = $\dfrac{8}{5}$ will treat as height for the base GHEF.

Now we know that , For a Cuboid ,

✏ Volume

= Base Area × Height

= $\dfrac{\cancel{25}}{\cancel4}\times\dfrac{\cancel8}{\cancel5}$ unit³

= (5 × 2) unit³

= 10 unit³

✺ Therefore :

Volume of the Cuboid = 10 unit ³

Answer 2

$</p><p>\tt{\huge{\pink{Hello!!! }}}$

Volm = Area of Base × Height = 10 unit^2
