​

Answer 1

$\boxed{\huge{\bf{\star{Correct \:Question \:-:}}}}$

☆ The area of 4 walls is 48 cm² whose length is 6cm and hight is 3 cm. Find the breath of four walls and volume of room ?

$\boxed{\huge{\bf{\star{AnswEr \:-:}}}}$

☆ Volume of room is 36 cm³

☆ Breadth of Four walls of room is 2 cm

$\large{\bf{\star{Explanation \:-:}}}$

$\large{\bf{\star{Formulas\:Related\:to\:question.............\:}}}$

$\sf{\:Formula\:of\:to\:find\:four\:walls\:of\:room\:-:}$

$\sf{A=2h(l+b)}$

$\sf{\:Formula\:of\:to\:find\:volume\:of\:room\:-:}$

$\sf{V=L \times B \times H}$

Here ,

Area of four walls = A

length of walls of room = l

breadth of walls of room = b

height of walls of room = h

volume of room = V

$\large{\bf{\star{Given\:-:}}}$

☆ Area of four walls = A = 48 cm²

☆ length of walls of room = l = 6 cm

☆ height of walls of room = h = 3 cm

$\large{\bf{\star{To\:Find\:-:}}}$

☆ Breadth of four walls .

☆ Volume of rooms.

$\large{\bf{\star{Solution \:-:}}}$

☆ Breadth of room -:

$\sf{\:Formula\:of\:to\:find\:four\:walls\:of\:room\:-:}$

$\sf{A=2h(l+b)}$

Area of four walls = A = 48 cm²

length of walls of room = l = 6 cm

height of walls of room = h = 3 cm

Now ,

$\sf{\rightarrow {2 \times 3 (6 + b) =48 cm²}}$

$\sf{\rightarrow {6 (6 + b) =48 cm²}}$

$\sf{\rightarrow { (6 + b) =\frac{48}{6}}}$

$\sf{\rightarrow { (6 + b) =8}}$

$\sf{\rightarrow {b =8 - 6}}$

$\sf{\rightarrow {b =2}}$

Therefore,

☆ Breadth of Four walls of room is 2 cm

Now ,

☆ Volume of room

$\sf{\:Formula\:of\:to\:find\:volume\:of\:room\:-:}$

$\sf{V=L \times B \times H}$

length of walls of room = l = 6 cm

height of walls of room = h = 3 cm

Breadth of Four walls of room is 2 cm

Now ,

$\sf{\rightarrow {2 \times 3 \times 6 }}$

$\sf{\rightarrow {2 \times 18 }}$

$\sf{\rightarrow {36 cm³}}$

Therefore,

☆ Volume of room is 36 cm³

Hence ,

☆ Volume of room is 36 cm³

☆ Breadth of Four walls of room is 2 cm

Answer 2

Answer:

Volume=36cm³

Breadth=2cm
