Question

Two cubes of side $6cm$ are joined end to end to form a cuboid. Then the volume of the resulting cuboid in ${cm}^3$ is

• A. $216$
• B. $116$
• C. $432$
• D. $418$

Answer 1

The correct option is C $432$

When the two cubes are joined length of the resulting cuboid is doubled and the height and width remain same.
$l=12cm$
$b=6cm$
$h=6cm$
Volume $=lbh=12\times 6\times 6=432{cm}^3$
