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/cm 3

cm cubed or cm^3

16.8 dm3

# Density of a block that measures 3 cm X 3 cm X 3 cm?

The volume of the block is (3 x 3 x 3) = 27 cubic cm. In order to find its density, you also have to know its mass. When you have that, divide it by 27 cm 3 , and the ans

# What is the mass of a block of osmium that measures 1.00 cm x 4.00 cm x 2.50 cm?

The volume of the block is (1 x 4 x 2.5) = 10 cm 3 The density of osmium is 22.61 g/cm 3 The mass of the block is (22.61 x 10) = 226.1 grams .

# How do you convert 3.5 cmx x 3 cms x 1 cms to inches?

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

Volume = 1.5 3 cc = 3.375 cc. Surface area = 6*1.5 2 cm = 13.5 cm 2 So surface area to volume ratio = 3.375 cm 3 /13.5cm 2 = 0.25 [cm]. Note that the ratio depends

# 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
