${\huge{\bf{\boxed{\blue{To Find :}}}}}$

Find the total surface Area of cuboid.

${\huge{\bf{\boxed{\orange{Formula \: used :}}}}}$

${\bf{\pink{Area \: of \: cuboid = 2(lb + lh + hb)}}}$

￣￣￣￣￣￣￣￣￣￣￣￣

${\huge{\bf{\boxed{\green{Solution :}}}}}$

Length = 7cm

Breadth = 3cm

Height = 2cm

${\huge{\blue{Area \: of \: cuboid :}}}$

${\bf{\orange{2(lb + lh + hb)}}}$

${\bf{\orange{ = 2(7 \times 3 + 7 \times 2 + 2 \times 3) }}}$

${\bf{\orange{ = 2(21 + 14 + 6)}}}$

${\bf{\red{\boxed{2 \times 41 = 82 {cm}^{2} }}}}$

So,

The cuboid has the surface area of 82 cm cube.
