Lost in the woods by a lake, you carve a block of wood into a cube shape 10 cm wide by 10 cm long by 10 cm high using a part of your body you conveniently identified as 10 cm before you got lost. You mark off the sides of the wood block in 1 cm increments. You want to determine if you'll be able to make a raft of this wood. Wading into the lake with this wood block, you find that 5.5 centimeters of the block stay submerged while the block is floating in water? If the lake water has a density of 1000 kg/m3, what is the density of this wood in kg/m? to two significant digits?
