Best answer
Correct Answer - Option 1 : 592.935 kg

Given  

Weight of a pebble = 2987g = 2.987 Kg

Weight of the box alone = 578 Kg

Formula used

Weight of the overall box = weight of box alone + 5 × weight of pebble

Calculation

⇒ Weight of the overall box = 578 + (5 × 2.987)

⇒ 592.935 Kg

∴ total weight of the box with pebbles is 592.935 kg
