Answer 2

Step-by-step explanation:

$\blue{ \bf{ \underline{ QUESTION} : }}$

The lateral surface area of a cuboid measuring 5cm × 4cm × 2cm

$\boxed{ \bold{ \huge{ Given}}}$

• Length = 5 cm

• Breadth = 4 cm

• Height = 2 cm

$\boxed{ \bold{ \huge{to \: find}}}$

• Area of the Cube

$\star{ \pink{ \underline{ \underline{Ｓｏｌｕｔｉｏｎ : - }}}}$

We know ➦

$\boxed{ \boxed{ \red{ \sf{Area \: of \: the \: Cube =2( Length × Breadth + Breadth × height + Health × Length}}}}$

$: \implies{ \sf{Area \: of \: the \: Cube = 2(5×4 +4×2+ 2 × 5)}}$

$: \implies{ \sf{Area \: of \: the \: Cube = 76 \: {cm}^{2} }}$

$\underbrace{ \therefore{ \orange{ Hance, \: Option \: (D) \: 76 cm² \: is \: Your \: ANSWER}}}$
