Question

If two cubes of side 6 cm are joined face to face, then find the volume of the resulting cuboid.

• A. $216c{m}^3$
• B. $442c{m}^3$
• C. $484c{m}^3$
• D. $432c{m}^3$

Answer 1

The correct option is D

$432c{m}^3$

$\text{Side of a cube}=6cm$

$\therefore \text{By joining two such cubes, the length of the so}$ $\text{formed cuboid (l)}=6\times 2=12cm$

$\text{Breadth (b)}=6cm$

$\text{Height (h)}=6cm$

$\therefore Volume=lbh=12\times 6\times 6c{m}^3$

$=432c{m}^3$
