When you calculate the density using your measurements, you get 8.78 grams/cm3. You measure the dimensions of the block and its displacement in a container of a known volume of water. Click Customize to make your own copy. Percent Error Definition The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract.
take 31.2-24.5 (actual minus thought to be count). You measure the sides of the cube to find the volume and weigh it to find its mass.
