well the volume of the board is 5.54*10.6*199 = 11686.076 cubic cm. and this volume of board weighs 2860 grams. Thus 1 cubic cm of the board would weigh 0.245 grams so the density is 0.245 g/cc
Volume = L*W*H = 1.10cm*2.0cm*1.10cm (interesting that length < width!) = 2.42 cm3 Density = Mass/Vol = 10.0/2.42 = 4.13 grams per cm3
Quite possibly a plane shape whose shorter dimension is 0.035 metres. The other dimension is the length which, conventionally, is the larger of the two.
Since density = mass/volume, D = 25/10 = 2.5g/cm^3

In this case.......... Density = mass in grams/centimeters cubed 5.54 cm * 10.6 cm * 199 cm = 11686.076 cm^3 Density = 28.6 grams/11686.076 cm^3 = 0.00245 grams/cm^3

A zero vector is a vector whose value in every dimension is zero.
Quite possibly a plane shape whose shorter dimension is 0.035 metres. The other dimension is the length which, conventionally, is the larger of the two.
You calculate density as mass / volume.
Density = 2.991 g/cm3

Since density = mass/volume, D = 25/10 = 2.5g/cm^3
