An oceanographic research vessel comes across a volcano under the sea. The top of the volcano is 450 ft below the surface and the sea floor is -6,700 ft. What is the height of the volcano?

6700 - 450 = ?

6250

To find the height of the volcano, we need to determine the vertical distance between the top of the volcano and the sea floor. We can calculate this by subtracting the depth of the sea floor from the depth of the top of the volcano.

We are given that the top of the volcano is 450 ft below the surface, and the sea floor is -6,700 ft.

To get the height of the volcano, we subtract the depth of the sea floor from the depth of the top of the volcano:

Height of volcano = Depth of top of volcano - Depth of sea floor

Height of volcano = 450 ft - (-6,700 ft)

To subtract a negative number, we can change the sign and add the numbers:

Height of volcano = 450 ft + 6,700 ft

Adding the numbers together, we get:

Height of volcano = 7,150 ft

Therefore, the height of the volcano is 7,150 ft.
