One cubic centimeter (1.0 cm3) of water has a mass of 1.0 10-3 kg.

(a) Determine the mass of 1.0 m3 of water.

b. Assuming biological substances are 98% water, estimate the masses of a cell with a diameter of 0.6 µm, a human kidney, and a fly. Take a kidney to be roughly a sphere with a radius of 5.0 cm and a fly to be roughly a cylinder 3.0 mm long and 1.8 mm in diameter.

does anyone know how to do

does anyone know how to do this problem?? if so i need help ASAP..PRONTO!!

1 m3=1 m * 1m *

1 m3=1 m * 1m * 1m

        = 100 cm * 100 cm * 100cm

So   1 m3 = 1000000 cm3

Now just put weight of 1cm3 =1.0 x 10-3 kg.

Weight of 1m3 = 1000000*10-3kg = 1000kg
