Question

find the total surface area of the cuboids of length breath and height as below 1) 12 cm,10 cm,5 cm

Answer 1

Hi !!

Length = 12 cm , Breadth = 10 cm and Height = 5 cm

Therefore,

TSA of cuboid = 2 ( LB + BH + HL )

=> 2 ( 12 × 10 + 10 × 5 + 5 × 12 )

=> 2 ( 120 + 50 + 60 )

=> 2 ( 230 )

=> 460 cm².

Hence,

Total surface area of cuboid = 460 cm².

Answer 2

Answer:

$\boxed{460 cm^2}$

______________________________________________

Step-by-step explanation:

We know that :

Let l be the length

l = 12 cm

Let b be the breadth

b = 10 cm

Let h be the height

h = 5 cm

Total surface area = $2 ( lb + bh + lh )$

$\implies 2 ( 12 cm\times 10 cm + 10 cm \times 5cm + 12 cm \times 5 cm )$

$\implies 2 ( 120 cm^2 + 50 cm^2 + 60 cm^2)$

$\implies 2 \times 230 cm^2$

$\implies 460 cm^2$

The surface area is =  $460 cm^2$

Hope it helps you
