$\bf\red{QuestioN:-}$

Find the total surface area of a cuboid whose length is 10 cm,  breadth is

8 cm and height is 5 cm​ .

$\bf\purple{AnsweR:-}$

Given :-

Length = 10 cm

Breadth = 8 cm

Height = 5 cm

To Find :-

Total surface area / TSA of the cuboid = ?

Solution :-

As we know ,

TSA of a cuboid = 2( lb + bh + lh )

Here,

Length = 10 cm

Breadth = 8 cm

Height = 5 cm.

⇒ 2 ( lb + bh + lh)

⇒ 2( 10×8 + 8×5 + 5×10)

⇒2( 80 + 40 + 50)

⇒ 2 ( 170)

⇒ 340 cm².

The required answer for your question is 340 cm^2.
