If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.

Length times width times height (lwh) is a way to figure out volume. If you try to do it with water displacement, the wood will adorn the water and ruin the calculations.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. Balsa, one of the least dense woods, has a density of 0.16 g/cm3 which is more than 3 times the "density" of your wood! So have you discovered a super-light wood species?
Measure it.
Answer: That probably would depend on the type of wood (e.g. ironwood vs balsa.?Answer: No wood is as heavy as iron. Iron would be heavier. Iron has a density of about 8 gram per cubic centimeter; would is usually lighter than water (density less than 1), but some woods are a little heavier than water.
