OCR: MEASURING DENSITY 10 MEASURE the density of an balance. The volume of a brick object, you need to know its mass shaped object such as a gold block, and its volume as density equals mass can be calculated by measuring its divided by volume. The mass ofan width (w), length 1 and height (h), object can ne measured easily on and then multiplying the three figures together Some irregular objects such as gold nuggets, can be placed After container of water The volume of water displaced when the object submerged equals the Before object' volume Mass and volume The mass an object can be measured on balance and its volume can measured with ruler measuring how much water displaces PRCHUMEDES PRINCIPLE full wher obiect
