Answer 1

$\bf\purple{QuestioN:-}$

Find the surface area of cuboid with length = 16.5 m , breadth = 4 m and

height = 20 m​ .

$\bf\pink{AnsweR:-}$

Given :-

Length = 16.5 m

Breadth = 4 m

Height = 20 m

To Find:-

The total surface area of the cuboid / TSA .

Solution :-

As we know,

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

Here,

Length = 16.5 m

Breadth = 4 m

Height = 20 m

⇒ TSA of cuboid = 2(lb +bh +hl)

⇒ TSA = 2 ( 16.5×4 + 4×20 + 20×16.5)

⇒ TSA = 2( 66 + 80 + 330 )

⇒ TSA = 2( 476)

⇒ TSA = 952 m²

The required answer for your question is 952 m².
