The length and breadth of a cuboid store are in the ratio 2 : 1 and its height is 3.5 meters. If the area of its four walls (including doors) is 210 m2, then what is the volume?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 700 m3
| Understanding | Application |
|
Given: Area of four walls (including doors) = 210 m2 Height = 3.5 m |
So, ⇒ 2(2x + x) × h = 210 ⇒ 2(2x + x) × 3.5 = 210 ⇒ 21x = 210 ⇒ x = 10 |
| Volume = l × b × h |
Hence, Volume = 20 × 10 × 3.5 = 700 m3 |
