A concrete patio is 5 meters long, 3.5 meters wide, and 8 centimeters thick. How many cubic meters of concrete were needed to build the patio?

Volume=legnth times withd tiem height

since it s only multiply, doesn't matter the order

very tricksy

they gave us the thickness in centimeters, not in meters

8cm=8/100m=0.08m

V=5*3.5*0.08

V=0.40*3.5

V=1.40

1.40 cubic meters (conversion is important)
