Question

the tunnel under the english channel that connects england and france is actually three separate tunnels built end to end. each is a half-cylinder that is 50,000 meters long and 4 meters high. how many cubic meters of dirt had to be removed to build the tunnel?

Answer 1

Answer: im not exactly sure but i think 600,000m³

Step-by-step explanation: multiply 50,000m by 4 to get 200,000m and then multiply that by 3 (because 200,000 is only one section of the tunnel)

and by doing that you get 600,000m and then add cubed onto the end because it says cubic meters
