Question

Find the lateral surface area of the cuboid whose dimensions are
$1=22$ cm, $b=12$ cm, $h=7.5$ cm

• A. $511{\text{cm}}^2$
• B. $510{\text{cm}}^2$
• C. $512{\text{cm}}^2$
• D. $513{\text{cm}}^2$

Answer 1

Answer: (B)

$510{\text{cm}}^2$

Given

Length $\left(l\right)=22$cm

Breadth $\left(b\right)=12$cm

Height $\left(h\right)=7.5$cm

Lateral surface of the cuboid $=2h(l+b)$

$\Rightarrow 2\times 7.5(22+12)$

$\Rightarrow 15\left(34\right)$

$\Rightarrow 510c{m}^2$

$\therefore$ The lateral surface area of the cuboid is $510c{m}^2$.

So, the answer is B: $510c{m}^2$.
