Question

piece of woods measure 5cm x 6cm x 3cm . If it weights 100g. Find it's density in S.I.​

Answer 1

Answer:

Given dimensions of the wood piece is : 4 cm by 3cm by 6 cm. = 0.04 m by 0.03 m by 0.06 m.

So volume of the given wood piece is (4*3*6) cubic centimetres. = 72 cc.

In SI units,volume is : (0.04*0.03*0.06)= (0.000072) metres cube.

Now , weight of the wood piece is : 108 grams = 0.108 kgs.

So, density is given by : mass/volume

Hence density of the given wood piece in SI units is = (0.108/0.000072) = 1500 kg/m^3.

Hope it helps!
