Question

find the cost of the painting think of the dimension 300 x 2 X 1.5 m @ rupees 20 per square metre

Answer 1

total place to be painted = 300*2*1.5m
= 900m^3

cost per sq.m = rs.20

converting into same units.......

m^3= 1000000cm
m^2=10000cm

so the cost painting 10000cm = rs.20

cost of painting 900000000cm = 900000000/10000*20= rs. 1800000

I don't think this is the answer.

if u know the correct answer please tell me.
