Question

Two cubes of edge 14 cm each are joined end to end to form a cuboid. Find the volume of the cuboid.

• A. $5469c{m}^3$
• B. $5588c{m}^3$
• C. $5488c{m}^3$
• D. $6488c{m}^3$

Answer 1

The correct option is C $5488c{m}^3$

Here, two cubes are joined to form the cuboid.
So, the volume of the cuboid = sum of volumes of the two cubes
$\therefore$ Total volume of cuboid
$=2\times \text{volume of cube}$
$=2\times (\text{edge}{)}^3$
$=2\times (14{)}^3$
= $5488{\text{cm}}^3$
