Question

B. A lava flow has a length of 45 km. It is 400 m wide and 5 meters thick. What is the volume of the

magma erupted? Give your answer in km.
How do I do this math style

Answer 1

The volume of the erupted magma is 0.09 cubic km.

Step-by-step explanation:

Since we have all values provided, and the requirement is that the result is in km, then we just need to convert all values in km.

Length - 45 km

Width - 400 m = 0.4 km

Thickness/Height - 5 m = 0.005 km

Now that we have all values converted to km, we just simply need to multiply them all and we will get the result in km:

45 x 0.4 x 0.005 = 0.09

We get a result of 0.09, and since it is the volume in question it is 0.09 cubic km.
