There is a box of cuboidal shape. The smallest side of the box is 40 cm and largest side is 80 cm. Which of the followeing can be volume (in cm³) of the box?
Answer & explanation
Correct answer: option 3
The third side must be between 40 and 80
40 < x < 80
Volume = 40 \(\times \) x \(\times \) 80
Minimum value of x = 40
Then volume = 40 \(\times \) 40 \(\times \) 80 =128000
Maximum value = 80
Volume = 40\(\times \) 80 \(\times \) 80 = 256000
128000 < Volume < 256000
This eliminates all options except c) 175000
