Please step by step if you could not read it it sais: A driveway 30m long and 5 m wide is to be paved with blacktop 3 cm thick. How much will the blacktop cost at $ 175 per cubic meter???
pleasee help

Answer 1

The volume of the asphalt needed is given by:

30 X 5 X 0.03 = 150 X .03 = 450/100 = 4.5 cubic meters

At %175 per cubic meter, that works out to 175 X 4.5 = 787.5 dollars.

Answer 2

find volume:
V = 30*5*.03 = 4.5 cubic meters

cost = volume * price /cubic meter
cost = 4.5*175 = $787.50
