(1 m³ fresh snow weighs 350 kg) In the morning I had to clear a path 69 m long and one meter wide. Snow fell overnight layer of thickness 19 cm. a) What is the roof volume? b) How many dm² of wallpaper is used to glue the roof, ie the cone shell? c) What is the weight of the roof if it is made of woo The cone side is 45 cm long and the base radius is 27 cm. 4 holes with a diameter of 40 mm are drilled into the board. The square oak board (with density ρ = 700 kg/m 3) has a side length of 50 cm and a thickness of 30 mm. Oak timber is rectangular shaped with dimensions of 2m, 30 cm and 15 cm. How many kg of seed are needed for sowing if the 1 m² will consume 25 g of seeds? The field has a rectangular shape with dimensions of 128 m and 350 m. What is the weight in kg of copper wire 200 m long with a diameter of 0.6 cm if the density of copper is 8.8 kg/dm³?Ĭalculate the volume of a gold horseshoe that weighs 750g. With the help of mathematical-physicochemical tables estimate what material the ball is made from. Calculate the volume, radius, and surface if the iron's density is h = 7.6g/cm³.Ĭalculate the density of the material that the prison ball is made from if you know its diameter is 15cm and its weight is approximately 2.3kg. Material of density of 1485 kg/m³ occupies a container volume of 65 cm³. Calculates the weight of the aquarium's water.Ĭalculate the plastic pipe's weight with diameter d = 70 mm and length 380 cm if the wall thickness is 4 mm and the density of plastic is 1367 kg/m³. Try to estimate the weight of the water in an aquarium 50cm long 30cm wide, when poured to a height of 25cm. What was the initial temperature of water t2 if the object's temperature and the water after reaching equilibrium was 35☌? We assume that the heat exchange occurred only between the lead o We placed a lead object weighing 0.4 kg and 250☌ in 0.4 L water. How much does a gold bar measuring 25cm, 8cm, and 37mm weigh? The basic SI density unit is kg/m 3Ĭonversion of a density unit in word math problems and questions The formula is ρ = m/V, where m = mass and V is volume. Density is defined as mass divided by volume. The symbol for density is ρ (Greek letter rho). You can also multiply a pennyweight by 1.555 to get an equivalent gram weight or divide a gram weight by the same 1.555 to get pennyweight.The density (the volumetric mass density, specific mass) of a substance is its mass per unit volume. You can substitute 20 for 31.1 to calculate pennyweight in our formula. There are 20 pennyweights in a troy ounce. Most people use grams for these calculations but some gold buyers use pennyweight (DWT) instead of grams.If you have 15.3 grams of 10K gold scrap, USD$1,600 divided by 31.1 equals USD$51.45, and that amount multiplied by.USD$30.01 multiplied by 5 grams equals USD$150.05. If you have 5 grams of 14K scrap and gold is USD$1,600.00 today, then USD$1,600 divided by 31.1 would equal USD$51.45.If you have 10 grams of 10K gold and you calculated the price at USD$21.44 per gram, then your scrap gold is worth 10 x USD$21.44 = USD$214.40. Multiply the price per gram by the weight in grams. If the 14K acid has no effect, but the 18k acid turns it brown, consider it to be 14k, and so on for other karat fineness tests. For example, if the 18K acid has no effect, but the 22K acid turns it brown, then consider your item to be 18K. If it is an unmarked item, go up to the 22K acid incrementally until it turns brown, and when it does, consider it to be the next lowest karat.If it completely disappears, it isn't even gold. 10 carat stone can be called either 10 points, or 1/10 of a carat. A hundreth of a carat is also called a point. Stones are measured to the nearest hundredth of a carat. One carat is equal to 1/5 of a gram (200 milligrams). If it is 10K, the 14K acid will turn it brown. Abbreviated 'ct.' and spelled with a 'c' is a measure of weight used for gemstones. If your item is indeed 14K gold, it will stand up to the acid and not change. For suspected 14K jewelry, rub the item on the stone and place a drop of 14K acid onto the mark it leaves.Kits can also be purchased with an accompanying scale. It will also come with a test stone, also known as a streak stone or touch stone, that will be made from many different materials, including novaculite or other types of flint material. A kit will come with 10K, 14K, 18K and 22K bottles of testing acid, which will normally be nitric acid. Supplies for this test can be purchased from online or physical jewelry suppliers for a small price, and are available separately or as a set.The first, the acid test, will require a gold testing kit or the individual parts that make one up (the acid and stone). You have two options here: the acid test and the Skey test. If you're still uncertain as to whether or not an item is gold after inspecting it with a magnifying glass, prepare to test it. Perform an acid test on any items you are unsure of.
