Question

a rectangular piece of wood measures 4 cm by 6 cm by 8 cm and bas a mass of 20 g. what is its density​

Answer 1

GIVEN

Dimensions of rectangle = 4cm×6cm×8cm

(I multiplied dimensions to get volume ) =

192cm^-3

density =?

SOLUTION

Density = mass /volume

= 20/192

density =0.1041666 g/cc

Density of water = 1000 g/cc

since it's density is less than that of water it will float.

HOPE IT HELPS YOU! !!!

Answer 2

Step-by-step explanation:

density=mass/volume

mass=20/1000kg

V=4m×6m×8m/100×100×100

=192/1000000

density= 20/1000kg×1000000/192m^3

=20000/192kg/m^3

104.16kg/m^3
