Is multiplying the length x width x height a good method to find the volume of a rock?
No. I say this because a rock is usually circular and not a perfect figure. :-)
What is the length width and height of a rock that has the mass of 45g and the volume of 15 cm3?
It's impossible to say definitively. One possible answer would be 2cm x 2.5 cm x 3cm, but it could also be a cube with sides equal to the cube root of 15, or an infinite number of other possibilities. (The mass is superfluous information for this question.)
If a right circular cylinder with radius 7 Cm contains 1077 cm cubed of water a rock is measured in the water and the level rises 3 cm what is the volume of the rock?
First obtain the height of the cylinder. Height = 1077/area of the base (i.e H = 1077 divided by pie-radius-squared) Next get how much water does 1cm of height contain. Take 1077/height. Therefore, volume of rock = 1cm height's volume x 3
What is the width of a wooden block?
That depends on how wide it is.What's the weight of a rock? What's the volume of a ship? How tall is a tree? We can't answer without more details.
How could you figure out the volume of an irregular solid such as a rock?
Fill a bowl of water that is bigger than the rock right to the top, add the rock, collect and measure the volume of how much water is spilt. Provide the rock is not porous or very soluble this will provide the volume of the rock.
How do you find out the volume of a rock?
Height times width times length equals the volume of the rock.

How many sheets of sheet rock for a room?
It depends on the size of the room. You need to measure the area to be covered and the area of the sheet rock
Does a ruler measure volume?
No, not with any degree of precision, anyway. A ruler is a linear measuring device; that is, it's good for measuring distances that are in straight lines. Volume is the amount of space an item occupies. To measure volume requires making three linear measurements, one for length, one for width(or depth), and one for height. But if your object is irregularly shaped, as a rock surely is, well, a ruler isn't going to do the job. Not very well, at least. You could grossly approximate the volume of the rock by measuring its dimensions roughly. In other words, if the rock is "about" six inches long and about three inches wide and about four inches high, then its volume is about 6 x 3 x 4 = 72 cubic inches (or inches cubed). But that is a very inexact calculation, because the rock is not a perfect parallelepiped. (What the heck is THAT? Double click the word for a definition.) A set of calipers would be better than a ruler, but your approximation would be only a bit better. To really determine the volume of the rock, you could submerge it in water and measure the amount of water it displaces. It might be a cool experiment to take a rock and approximate its volume with a ruler, calipers, and a beaker of water, to see how accurate (or inaccurate) each method is.
How would you find the volume of an irregular shaped object like a rock?
You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
Formula to calculating volume of granite rock before blasting on quarry?
The length times width times the depth of the holes of the bench times the amount of emulsion in the holes
Describe a method that the student could use to find the volume of this rock?
You can find the volume of a small rock in no time at all. Just fill up a container that is marked by volume with water and record the volume. Then drop the small rock inside the container. Record the new volume. Find the difference between the new and old volumes. This is the volume of the small rock. You could do this in any liquid.
When a rock is placed in a graducated cylinder containing water the height of the water will?
The height of the water will rise a level equal to the volume of the rock.
What is the length width and height of a rock that has the mass of 45g and the volume of 15 cm3?

What is density measured with?
Density is the Mass (weight) of a unit of Volume. In the Metric system it is usually stated as the number of GRAMS per CUBIC CENTIMETRE ( gm/cc) A cc is a cube of 'stuff' having a length, and a width, and a height of 1 centimetre. Pure WATER has a density of 1 gram/ cc . Steel density is approx. 8gram/cc A cc and a ml both occupy the same VOLUME . If you put a rock into a FULL container of water, then the overflow of water will be exactly the same as the Volume of the Rock. Measure the quantity of ml which overflowed, and that will be the cubic centimetre volume of that Rock. Now weigh the Rock and calculate its gram/cc Density
