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
