Correct Answer - Option 1 : This is 337.5% of the volume of the original box.
Concept Used:
Volume of Cuboid = L × B × H
Calculation:
Let the dimensions of the boxes be L, B and H respectively
Original Volume = LBH
New dimension after increasing the dimensions by half of the original size = (1.5L × 1.5B × 1.5H)
New volume = 3.375LBH
Required percentage = (3.375LBH/LBH) × 100%
⇒ 337.5%
∴ Required percentage is 337.5%
