A cuboidal tank has 25000 liters of water. If the depth of the cuboid is 1/5 of its length and breadth is 1/8 of its length, then the length of the tank is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 10 m
| Understanding | Application |
| Tricks |
Let the length of the cuboid = 40x m So depth = 8x m & breadth = 5x m |
| Now |
lbh = 25000 40x × 5x × 8h = 25000 ⇒ 1600x3 = 25000 ⇒ x3 = 250/16 ⇒ x3 = 15.625 ⇒ x = 2.5 |
| Hence |
length = 40 × 2.5 100 m |
