Question

The internal dimensions of a hall are in the ratio 7 : 5 : 3. If the volume of the room is 2835 m2, then find then length of the hall.​

Answer 1

Answer:

Length of hall = 21 m

Step-by-step explanation:

The length, breadth and height of the hall are in the ratio 7 : 5 : 3.

So, length, breadth and height of the hall is 7x, 5x and 3x respectively.

Volume of the room = l × b × h

2835 = 7x × 5x × 3x

2835 = 105x³

x³ = 2835 / 105 = 27

x = 3

Length of hall = 7 × 3 = 21 m
