Question

Two cubes of edge 4 cm each are joined end to end to form a cuboid. Find the volume and the total surface area of the cuboid.

• A. 136 $c{m}^3$
• B. 132 $c{m}^3$
• C. 125 $c{m}^3$
• D. 128 $c{m}^3$

Answer 1

The correct option is D 128 $c{m}^3$

Volume of the cuboid = 2 × Volume of one cube
$=2\times 4^3$
$=2\times 64c{m}^3$
$=128c{m}^3$
