Answer:
And over time, volcanoes made from low lava viscosity are wide and have a shallow slope; these are known as shield volcanoes.

9,600 cubic miles
Mauna Loa is the largest volcano on Earth with an estimated volume of 9,600 cubic miles (40,000 cubic kilometers). It makes half of the area of the Island of Hawaii. Mauna Loa began to form nearly a million years ago. There is a caldera, Mokuaweoweo, at the summit and rift zones extend to the northeast and southwest.
