Answer:
energy required = 553772 kJ
Explanation:
we know that
1 m = 100 cm
1 m³ = 1000 L
so volume will be
water volume = 1,658 × m³
water volume = 1.658 m³
so water volume we can say = 1,658 liters of water
and
we know that 1 mg of water require = 334 J energy
so here here we can say 1 L = 334 kJ energy
as that 1658 L energy require = 1658 × 334 kJ
energy required = 553772 kJ
