Now do the same procedures for the remaining block types, going across the top row and then the bottom row. Answer all questions numerically (aka, don't type the units). All measurements should be as accurate and precise as possible with the given equipment.
HINT: To get an accurate volume reading, you need to make sure the block is entirely submerged. To do this, you can either click and drag it under water, or click "Reset" up top and change the the fluid density until you find a density at which the block sinks. Make your volume measurements in this new fluid. You can always turn the fluid back to water with the blue button later.
If your answer is a decimal, be sure to include the leading zeroes as shown here in bold: 0.12345
