What does a 4inches x 8inches x 16inches hollow concrete block weigh?
you need to have the density of the concrete block. after you find it, use the formula density = mass/volume --> mass = density x volume to calculate the mass. if you want to find the weight in Newtons, use W = mg where m is the mass and g is 9.81N/kg. that will give you the weight of the block. for this case, the volume is 4m x 8m x 16m ( i assume it is in metres cos no units were given) = 512m^3. find the density in kg/m^3 and use the above formula mass = density x volume to calculate the mass. use W = mg to find the weight of the block in Newtons.
What is the density of A rectangular wooden block that measures 10 cm by 4 cm by 2 cm when placed in water and it is floating horizontally with its bottom face 1 point 65 cm below the surface?
It is 0.825g/cm^3. Use the area of the wood to find the area of the water displaced with a depth of 1.65. This will give you the volume of the water and multiply that by it's density(1000kg/m^3) to reveal the mass of the water. The mass of the water should be equal to the mass of the wood. Divide this mass by the volume of the wood(not the water segment), which will give you the density of the wood block. Be careful with the unit conversions, you may do the right math, but still have the wrong answer.

How do you use dreidel in a sentence?
Example sentence - My grandfather taught me how to carve a dreidel from a block of wood.
The mass of a wood block is 33.3 grams It has a volume of 6.02cm What is the Density?
Centimeters are not the right units to use for volume. Although, if it is centimeters cubed(cm^3) then it would be: 33.3g / 6.02cm^3 = 5.53156 g/cm^3
