Question

The length of a coldstorage is double it's breadth.Its height 3m. The area of it's four wall(including doors) is 108m^2.Find it's volume.​

Answer 1

Answer:

Given,

l=2b and h=3 m

Now, Area of four walls = 108 m

3

2(l+b)h=108

18b=108

b=6 m

Therefore, l=2b=12 m

Hence, volume of the cold storage = lbh=12×6×3=216 m

_________________________________________

❥ Let the length, breadth and height of the coldstorage be L m, b m and h m respectively.Then

l = 2b (given) and h =3m.

${\boxed{\pink{\tt{Now, \: area \: of \: the \: four \: walls = 108 {m}^{2} }}}}$

⇒ 2(l+b)h = 108 ⠀⠀⇒2(2b+b)×3=108

⇒ 18b = 108 ⠀⠀⠀⠀ ⇒ b= 16

∴ l = 2b ⠀⠀⠀⠀⠀⠀⠀ ⇒ l = 2×6m = 12m

Hence, Volume of a cold storage = ${\boxed{\pink{\tt{ l \times b \times h = 12 \times 6 \times 3 \times = {216m}^{2} }}}}$
