A block has a volume of 0.09 m3 and a density of 4,000 kg/m3. What's the force of gravity acting on the

block in water?

A3,038 N
B882 N
C2,646 N
D3,528 N

density = (mass) / (volume)
4,000 kg/m³ = (mass) / (0.09 m³)
(4,000 kg/m³) x (0.09 m³) = mass
mass = 360 kg 
force of gravity = (mass) x (acceleration of gravity) = (360 kg) x (9.8 m/s²) = (360 x 9.8)  kg-m/s² =   3,528 newtons .
