Question

The volume of a cuboid is $440{cm}^3$ and the area of its base is $88{cm}^2$. Find its height.

• A. $5cm$
• B. $7cm$
• C. $9cm$
• D. $4cm$

Answer 1

Answer: (A)

$5cm$

Let length breath and height of cuboid be l,b and h respectably.
therefore$l\times b=88{cm}^2⟶\left(1\right)$
and $l\times b\times h=440{cm}^2⟶\left(2\right)$
from (1) and (2), we get
$88\times h=440h=5cm$
