Question

A certain household has consumed 250 unit of energy during a month how much energy is this in joule

Answer 1

1 unit = 1 kWh

= 3.6 × 10^6 Joule

250 units = 250 kWh

= 250 × 3.6 × 10^6 Joule

= 900.6 × 10^8 Joule

= 9 × 10^8 kJ

Answer 2

Answer:

• 900 × 10⁶ J.

Explanation:

Given:

• A certain household as consumed 250 unit of energy during a month.

To find:

• How much energy is this in joule.

Solution:

We know,

• 1 unit = 1 kilowatt hour: 3.6 × 10⁶ Joule

We have,

• 250 units = ?

⇒ 250 units = 250 × 3.6 × 10⁶ J

⇒ 250 units = 900 × 10⁶ J

∴ 250 units = 900000000 J/9 × 10⁸ kJ.
