- You will be using these rules in your calculations. As an example of a sample calculation, find the volume of a rectangular solid: V = Lx W x H V = (25.95 cm)(5.87 cm)(83 cm) V = 13000 cm³ = 1.3 x 10“ cm3 Note that when you do this calculation in your calculator, you will have an answer of 12643.0995. However, the 83 cm limits your answer to 2 significant figures, so you must round the final answer to 2 significant figures. Remember you need to keep the place value of the significant figures! The scientific notation helps clarify that none of the zeros are significant.The density of ordinary air is 1.19 g/L. What is the mass, in kilograms, of the airin a room that measures 14.5 ft x 16.5 ft x 8.0 ft?(Hint: Density is defined as d= m/v, so you need to find the volume of the roomand solve for the mass in the density equation. Make sure you do the appropriateconversions to carry out your operations. Use the correct number of significantfigures to express your answer).One cm3 of gold is 19.32 g. What is the density (ratio of mass to volume) of gold inkg per m3 ? I know the answer is 19.32x10^3 but can someone tell me the steps to get there?
