How can you calculate surface density if the volume density is 1.4 g/cm3
Surface area of the roof times depth of snow gives volume of snow. Take a sample of snow and weight it to determine density (since the density of snow can vary quite a bit). Density times volume equals weight.
Air density is higher near the surface of the Earth. As you climb away from the surface, the pressure decreases.
An epiphyte is a plant that lives on another plant. Whereas most plants anchor themselves in soil and derive nutrients from soil, an epiphyte attaches itself to the surface of a tree trunk, branch, leaf, or some other part of a plant. From there the epiphyte collects nutrients usually from water running off the substrate plant or from debris wafting in the air. Ferns are a large, variable group of plants. Some, but not all, epiphytes are ferns. Some, but not all, ferns are epiphytes. Some plant groups are more likely to have epiphytic species than others, and the ferns are one of those groups. For example, it's not surprising to learn about a fern, orchid, or bromiliad that is epiphytic. In fact, a very large portion of orchids and bromiliads are epiphytes. But it's very unlikely that you'll ever hear about an epiphytic pine tree. Pines simply can't have an epiphytic growth habit.

A triangle is a flat area, therefore it has a surface area, not a volume. Density is unrelated to the problem; you would need some additional information to calculate the surface area.
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.

You cannot These are different concepts. you need a volume and density to calculate mass, surface area provides neither (a cube and a sphere with the same surface area have different volumes and, had they been made of the same material, would have different masses).
Force it below the surface of water and measure the force required.
This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.

as we know the relation between surface tension and temperature is inverse, and that of temperature and density also has inverse proportion, then it is clear that the '''surface tension is directly proportion to the density'''.
