A block of wood measures 3m�1.5m�80cm. How much would it cost to paint it at the rate of rs 40 per square cm?

A block of wood measures 3m�1.5m�80cm.
= 300cm X 150cm X 80 cm

Surface Area = 2(lb+bh+lh)
2*(300*150+150*80+80*300)
=160,000 cm^2
cost to paint it at the rate of rs 40 per square cm?
multiply the area by the rate
