Question

Calculate the total surface area of a cuboidal brick. Given that its length, breadth and height are 20 cm, 10 cm and 5 cm respectively.


please answer as soon as possible ♡♡♡​

Answer 1

Answer:

1000cm³

Step-by-step explanation:

Area of a cuboid=L X B X H

So,20cm X 10cm X 5cm

=>1000cm³

Answer 2

according to the question

length of the brick =20cm

breadth of the brick=10cm

height of the brick=5cm

formula of total surface area=

2(lb+bh+hl)

putting values in formulae

2(20*10+10*5+5*20)

2(200+50+100)

2*350

$700cm^2$

therefore the total surface area of brick is $700cm^2$
