What is the mass of a magnesium block that measures 2.5 cm x 3.5 cm x 1.5 cm?

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

You need to know the density o f Mg
D = Mass/Volume

Mass = Density * volume

Density= 1.74 grams per cubic centimeter
Volume = 2.5 * 3.5 * 1.5

Mass = Density * volume

How do you find mass of lead block 20 cm x 20cm x 10 cm?

Find Volume (20x20x10)=400cm^3 Density of Lead is 11.34 g/cm^3 Use Formula D=Mass*Volume Divide volume over density 4000/11.34 352.7336861 grams (not using sig. figs)

The density of magnesium is 1.74 g centimeters3 the mass of a magnesium block that meaasure's 2.5 centimeters x 3.5 centimeters x 1.5 centimeters is how many grams?

2.5 cm x 3.5 cm x 1.5 cm = 13.125 cm^3 13.125 cm^3 x 1.74g/cm^3 = 22.8375 grams Mg

What is the sq cm of 4 x 2 x 1.5 cm?

You've given three figures here which makes me think that they are the sides of a three dimensional figure. But you've asked for the square centimetres. This is not possible.

If a block of wood measures 2.55 cm wide 3.5 cm long and 1.5 cm in thickness weighing 300.5g what is the density of the block?

  denisty= mass/volume volume = l*w*h   so 300.5g / (2.55cm*3.5cm*1.5cm) = 22.4 g/cm3

cm cubed or cm^3

16.8 dm3

If a rectangular block weighs 5 grams and measures 10 cm x 4 cm x 2m what is the density?

D=M/V If you mean the mass is 5 grams then: V=10 x 4 x 2 V=80cm^3 D=5/80 D=.0625 g/cm^3 If you mean the block WEIGHS 5 grams then: M=Weight/9.8=.51 V=80 cm^3

A block of an unknown metal measures 5 cm x 3 cm x 2 cm the block as a mass of 235 g Of what metal do you think the block is made. Would this metal flaot or sink in mercury?

This metal would float in mercury because mercury is so dense that it would support almost any force that put upon it.

How big is a cyst measuring 4.5 x 2.5 x 5.1 cm?

It will probably surprise you to know that it is exactly 4.5cm*2.5cm*5.1cm.

What is the surface area to volume ratio in 1.5 cm x 1.5 cm x 1.5 cm?

Volume = 1.53 cc = 3.375 cc. Surface area = 6*1.52 cm = 13.5 cm2 So surface area to volume ratio = 3.375 cm3/13.5cm2 = 0.25 [cm]. Note that the ratio depends on the unit

What is the mass of a block of gold that measures 20 cm x 15cm x 10cm?

Specific gravity of gold = 19.3 (so density = 19.3 grammes per cubic centimetre) Volume of gold block = 20*15*10 = 3000 cubic centimetre Mass of gold block = 3000*19.3 = 5790

2.8 x 2.5 = 7.0

3.5 x 3.8 = 13.3
