A student is investigating volume and density. The student has a box, as shown in , a balance, a rule and some dry sand. shows the dimensions of the inside of the box. 4.0 cm 4.0 cm 5.0 cm (not to scale) Calculate the volume of sand needed to fill the box. volume of sand = cm3 The student measures the mass of the box when empty and when filled with sand. quantity mass / g mass of box filled with sand 216.0 mass of empty box 40.0 Calculate the mass of the sand in the box, using her results. mass of sand = g Calculate the density of the sand. density of sand = g / cm3 A miner has a bag containing a mixture of gold dust and sand. Gold has a density of 19.3 g / cm3. He heats the mixture until the gold melts. Predict whether the sand will float on top of the molten gold. Explain your answer.

A student wants to find the density of a small stone. shows a measuring cylinder, containing water, placed on a balance. measuring cylinder water reading K balance reading L The stone is placed in the water as shown in . reading M stone reading N The student determines the mass of the stone and its volume. Use the labels K, L, M and N from and to show how to calculate the mass and the volume of the stone. mass of stone = reading minus reading volume of stone = reading minus reading The student obtained the following values. 78.0 g mass of stone = 30.0 cm3 volume of stone = Calculate the density of the stone. Include the unit. density = unit

A student has a pile of A4 paper for his computer printer. shows the dimensions of the pile of paper. 30.0 cm 20.0 cm 5.0 cm (not to scale) The pile contains 500 sheets of paper. Calculate the average thickness of one sheet of paper. average thickness = cm Show that the pile of paper has a volume of 3000 cm3. Use the information shown in . The student measures the total mass of the paper in the pile. State the name of a device used to measure mass. The mass of the paper in the pile is 2400 g. Calculate the density of the paper. density = g / cm3
