What is the weight of a sheet of glass 75 cm x 120 cm and 2 mm thick if one cubic meter of glass weighs 2500 kilograms? What is the weight of cast iron with a volume of 3575 cubic centimeters? The density of the cast iron is 7600 kg/m 3 What is the volume of kerosene if its weight is 8g? The density of kerosene is 780 g / l The model is made from exactly the same material as the original no numbers need to be rounded. How high is the model of the tower's weight of 1 kg? (State the result in centimeters). The tower's height is 300 meters, and its weight is 8000 tons. How many kilograms is an ice cube with an edge length of 6 dm heavier than it? The cube with an edge length of 2 dm weighs 7.2 kg. The sculptor composes an ice city from ice cubes. What is the mass of a pole with the shape of a regular quadrilateral prism with a length of 1 m and a cross-sectional side length of a = 4.5 cm made from iron with density ρ = 7800 kg/m³? How many liters of water do we need if freezing water increases its volume by 10%?Ĭalculate the thickness of the copper plate with a density of 8.7 g/cm³ measuring 1.5 meters and 80 cm, and its weight is 3.65 kg.Ĭalculate the radius of an iron ball with a density of 7.8g/cm³ and a mass of 7kg. We want to cover a rectangular rink with dimensions of 55 m and 25 m with a 4cm thick layer of ice. What is the weight of the glass door panel if it is 5 mm thick, 2.1 m high, and 6.5 d wide? The density of glass is 2.5 kg/dm³. What is the maximum density that may have material with which we could fill this whole wagon? b) what amount of peat (density 350 kg/m 3) can carry 15 wagon The wagon can carry a maximum weight of 30 tonnes. 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). The density (the volumetric mass density, specific mass) of a substance is its mass per unit volume.
