Question

length is equal to 6cm and breadth 3 cm height 2 cm find the total surface area of a following cuboids​

Answer 1

$\mathfrak{ \huge{ \red{ \underline{ \underline{ANSWER}}}}}$

• Given :

=> length l = 6 cm

=> breadth = 3 cm

=> height = 2 cm

• To Find :

=> Total surface area of cube

• Formula :

=> Total surface area of cube is given by

$\: \: \: \: \: \: \: \boxed{ \sf{ \bold{ \pink{s = 2(lb + bh + lh)}}}}$

• Calculation

$\implies \sf \: s = 2(18 + 6 + 12) = 72 \: {cm}^{2} \\ \\ \boxed{ \red{ \sf{s = 72 {cm}^{2} }}}$

Answer 2

Answer:

72 cm²

Step-by-step explanation:

Cuboid has 6 faces.

length = 6cm

breadth = 3cm

height = 2cm

Surface area of the smaller face = b x h = 6cm²

there are two small faces = 6 x 2 = 12cm²

area of 2 opposite larger faces =2( l x h )=2( 6 x 2) = 24cm²

area of the other 2 opposite larger faces =2(l x b)=2(6 x 3)

=36cm²

Total SA = 36+12+24= 72 cm²
