180×800=144000w
180× ₹= answer
i hope it is the correct answer

we need to multiply 800 and 180 and we will get 144000 and that will be the energy and then finally 144000 × 3.00 gives the answer i.e., 4,32,000rs
whom are u asking ? me?
but why shouldn't we do in this method- H=p×t =0.8 kW×
sorry
0.8 kW× 6= 4 unit
cost of energy is 4 × 30 × 3
i am sorry but i am not sure about this answer.
