# 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. …Square centimetres would give you the area of a flat object, but you'd need cubic centimtres for a three dimensional one. The answer to the maths in your question is 12, but they are not square centimetres.

# 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

# What is Cm x cm x cm?

cm cubed or cm^3

# A wood block has the dimensions of 2.0 cm x 1.5 cm x 0.56 cm what is its volume in cubic decimeters?

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 … D=.51/80 D=.006375 g/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.

# 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 …of measurement. === Note also that the above presentation apparently became top-heavy, causing the ratio to suddenly flip over during the process. Surface area = 6 x (1.5)2 Volume = (1.5)3 Area/Volume = 6 x 1.52/1.53 = 6/1.5 = 4 cm-1
