The length, breadth and height of a room are in the ratio of

3: 2: 1

. If its volume be

1296 {m}^{3}

, find its breadth.

Solution:

\;\text " (d) Let length, breadth and height of a room are "\; 3 x,

2 x \;\text " and "\; x, \;\text " respectively. "\;

\;\text " Then, "\; \;\text " volume of room "\;=1296

⇒ \;\; \;\; 3 x × 2 x × x=1296

⇒ \;\;6 x^{3}=1296

⇒ \;\; x^{3}=216

∴ \;\; x=6

∴ \;\text " Breadth of room "\;=2 x=2 × 6=12 {m}
