Explanation:
Surface area is 54cm²
, volume is 27cm³
and surface area-to-volume ratio is 2
Explanation:
If s is the side of a cube, then its surface area is 6s²
and its volume is s³
Hence, if the sides of a cube are 3 inches long
its surface area is
6×3²
=6×9
=54cm²
,
its volume is 3³=27cm³
and surface area-to-volume ratio is
54/27=2
Answer:
The path of a total eclipse that is swept out by the umbra shadow of the moon on the earth. The umbra is the dark center portion of a shadow. The Moon's umbra causes total solar eclipses, and the Earth's umbra is involved in total and partial lunar eclipses.

Volcanoes play an important role in creating land since they are the sources of magma, which once above ground normally cools to create new land. In the ocean, this land normally forms at divergent and convergent boundaries or hot spots. At divergent boundaries (where two plates move apart), magma constantly erupts along a trench deep below the ocean's surface. This magma rarely piles upward and instead is pushed to both sides of the trench. This is how new seafloor forms. Convergent boundaries can create island arcs like Indonesia as magma erupts bit by bit. Hot spots occur in the middle of plates. They are instances where the mantle pierces through the crust and begins to erupt directly onto to seafloor. Over time, these eruptions will pile up and create underwater volcanoes until they potentially make it above sea level, thereby forming an island. This is how Hawaii was and continues to be formed.
