Your friend finds a block of copper and wants to cash it in? But first you need to know the mass of the block? The block is 10 cm in height, 5 cm in width and 20 cm in length. The going rate for Copper is about $6.00/kg. (Cu D - 8,920 kg/m , Conversion Units: 1 m = 1x10 cm) a.) Calculate the mass of the Copper block? Then calculate the money you will make? b.) Since you found the mass of the block. What is the pressure the block is exerting onto the ground? If the block is standing as shown in the picture. Use the mass in part (a). Hint you need to calculate the weight (Force) first before finding the pressure. (g = 10 m/s)? Units of Pressure need to be in N/m-, Unit Conversion: 1 m = 1x10* cm-) 10 CM 20 CM 5 CM
