Sorry, had to edit. OK now I think.
Use the formula: Density = Mass / Volume
Therefore, Mass = Density * Volume
= 2.4 * 3^3
= 64.8 g = 0.0648 kg
Now, Weight = Mass * Acceleration due to gravity
= 0.0648 * 10
= 0.648 N (Answer is A.)
2.4 x 3 x 3 x 3 = 64.8 gms or 0.0648 kg. Assuming the gravitational pull as stated (factor of 10) the answer would be "A".
Mass = (3cm) (3cm) (3cm) (2.4 g/cm3)
Mass = 64.8 grams = 0.0648 Kg
Weight = (0.0648 kg) ( 10 m/s2)
Weight = (0.648 KN) = 648 N
