Question

find the total surface area of a cuboid whose
length =1.2m
breadth=30cm
height =15cm​

Answer 1

Answer: use the formula..2(lb+bh+lh)

Step-by-step explanation:

length=1.2cm

breadth=30cm

height=15cm

2(1.2*30+30*15+15*1.2)

simplify and u will get d ans....sorry that at first wrote wrong answer bcuz i was in a hurry to complete my target...am sorry:(

(* symbol indicates multiplication)

hope u understood my answer...

Answer 2

Answer:

11700cm²

Step-by-step explanation:

Given :

• Shape: Cuboid.
• Length: 1.2m
• Breadth: 30cm.
• Height: 15cm​.

So,

We know that :

Surface Area of Cuboid :

$\bigstar\;\boxed{\bf 2lw+2lh+2wh}}}$

We have,

• Length: 1.2m
• Breadth: 30cm.
• Height: 15cm​.

We have to convert the given length to cm.

⇒ 1.2 × 100

⇒ 120cm.

Now, Putting values in formula,

$\implies \sf 2\times120\times30+2\times120\times15+2\times30\times 15$

$\implies \bf{11700}$

So,

The total surface area of this cuboid is 11700 cm²
