8. An oceanographic research vessel comes across a volcano under the sea. The top of the volcano is 300 ft below the surface and the sea floor is -7,200 ft. What is the height of the volcano?
7200 - 300 = ___ feet
To find the height of the volcano, we need to calculate the difference in depth between the top of the volcano and the sea floor.
Given:
Top of the volcano = 300 ft below the surface
Sea floor = -7,200 ft
To determine the height of the volcano, we subtract the depth of the sea floor from the depth of the volcano's top.
Height of the volcano = Top of the volcano - Sea floor
Height of the volcano = 300 ft - (-7,200 ft)
To subtract a negative number, we can rewrite the calculation as addition:
Height of the volcano = 300 ft + 7,200 ft
Calculating the sum:
Height of the volcano = 7,500 ft
Therefore, the height of the volcano is 7,500 ft.
