Here is the information you are given and a corresponding equation demonstrating the relationship between the given information and the unknown.
Vtotal = Vwater + Vsand = 42cm3
Here is the given equation rearranged (by subtracting the volume of water from both sides) to target the unknown information (volume of sand).
Vsand = Vtotal - Vwater
Plugging in the given info to the equation yields your answer.
Vsand = 42 - 20
Vsand = 22cm3
A cylinder with a radius of 6.5 centimeters and a height of 10 centimeters has a volume of 1,327.32 cubic centimeters.
a graduated cylinder
The answer depends on the cylinder.
The volume is 62.83cm3
To determine the volume of an irregular object using graduated cylinders, you fill a graduated cylinder with water right to the top, then submerge the object in the water. Measure the water that overflows using a second graduated cylinder, and read the water level in it in cc's or cubic inches. That is the object's volume.
The cylinder containing gold.
No. You mesure volume with a graduated cylinder.
Graduated cylinder
One way to figure this out is to put the object in a graduated cylinder containing water and measuring the changes in the volume of the water.
