pls find the 3rd question *-*​

Answer 1

Answer:

$\huge\rm{\underline{\underline{Given→}}}$

• $\rm\green{Side\:of\:cube=20cm}$

$\huge\rm{\underline{\underline{To\:Find→}}}$

$\rm\purple{→Lateral\:and\:total\:surface\:area}$

$\huge\rm{\underline{\underline{Answer→}}}$

$\large{\underline{\boxed{\rm{\dashrightarrow\:TSA\:of\:cube=6a^2}}}}$

$\large{\underline{\boxed{\rm{\dashrightarrow\:LSA\:of\:cube=4a^2}}}}$

Where a=side of cube

NOW TSA:-

$\rm\blue{→6a^2}$

$\rm\blue{→6(20)^2}$

$\rm\blue{→6\times400}$

$\rm\blue{→2400cm^2}$

${\boxed{\boxed{\rm{\pink{→TSA=2400cm^2✔}}}}}$

AND LSA:-

$\rm\blue{→4a^2}$

$\rm\blue{→4(20)^2}$

$\rm\blue{→4\times400}$

$\rm\blue{→1600cm^2}$

${\boxed{\boxed{\rm{\pink{→LSA=1600cm^2✔}}}}}$

Hence the TSA and LSA of the given cube are 2400cm² and 1600cm² respectively. Which is the required answer.

HOPE IT HELPS.
