Science Help please??? Urgent!!!!?

They have the same mass. 1kg = 1 kg

Oak is a form of wood and most forms of wood float in water, meaning the density is less than 1

Lead has a density of about 11 ... So D = mass/volume ... the volume is smaller for the lead than the oak.

They have the same mass assuming their weights were both established by scales on earth. Since lead is more dense than oak it require less volume to equal 1 kilogram than does oak. Since oak floats its density is less than water and since lead sinks, its density is greater.

Since lead has a density of 11.34 g/cm^3 and the density of white Oak is 770 kg/M^3 one can determine the volume of each necessary to have a weight (on earth) of 1 kilogram.

Since 1 kilogram = 1000 g, 1000/11.34 = 88.18 cm^3 of lead will equal 1 kg. This is a cube with side equal to 4.45 cm.

Since 1 cubic meter (1,000,000 cm^3) of oak weighs 770 kg, 1 kg of oak will require a volume 1/770 or 0.00129 cubic meters or 1298.7 cm^3. This is a cube with sides of 10.91 cm.

They have the same mass, but you cannot determine the volume without the of length, hight, and width.

Volume=lwh

They have the same mass. It's like asking which is heavier: a pound of feathers or a pound of bricks.
