Question

If you have a block of wood that is 4cm wide ,6cm long and 10cm high and it weighs 100 grams what would happen to the volume if yhe wood block is cut into 2 equal halfs

Answer 1

It would make both half 4cm to 2cm wide, and 6cm to 3cm long, 10cm to 5cm hight it would split in half

Answer 2

It doesn't matter whether you cut the length, the width, or the height, straight, slanted, or curly-cue.  You've still got 240 cm^3 of total volume there, and if the two pieces are equal, then the volume of each piece is 120cm^3, and the mass of each piece is 50 grams, and they both float in water.
