A wooden block immersed partially into water. There were 15% of the total volume of the block exposed and 85% of the total volume immersed in water. Calculate:
a) the density of the wooden block. (Unit= kg/m3)
b) the weight of the wooden block in the air if there were 280 N of water displaced (Unit=N)
c) the total volume of the wooden block. (Unit=m3)
