Lava is the general term for igneous rock that forms on the surface. Extrusive igneous rock is the more technical term.
Magma. Magma rises towards the surface when it's less dense than rock around it. Otherwise, it collects in magma chambers and cools, forming igneous rock.
Magma. Magma rises towards the surface when it's less dense than rock around it. Otherwise, it collects in magma chambers and cools, forming igneous rock.
Magma that cools quickly forms into igneous rock, when it cools quickly it becomes a lava rock. Lava cools very quickly at first and forms a thin crust that insulates the interior of the lava flow.

Yes. Lava is the name given to magma that has reached the surface via eruption. The word 'lava' is also used to denote the solidified product of lava - extrusive igneous rock.
Lava is the name given to any still molten rock that is extruded onto the Earth's surface. When it cools it becomes an extrusive igneous rock such as basalt.

Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.
These are extrusive igneous rocks with an aphanitic texture.

It should be relatively easy to find the surface area of a box when you are given the surface area.
