What is Cube formula?
Cube of any digit, forms by multiplying the digit by itself three times. For instance, to find the 5^{3} we need to multiply 5 three times: 5 \times 5 \times 5 = 125. Note: we write down “5 cube” as 5^{3} (the little 3 means the number appears three times during the multiplication process.
How does volume affect surface area?
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Is the surface area of a cube the same as the volume?
Explanation: This problem is relatively simple. We know that the volume of a cube is equal to s3, where s is the length of a given side of the cube. Since the sides of a cube are all the same, the surface area of the cube is equal to 6 times the area of one face.
What is the difference between perimeter area and volume?
Remember that perimeter means the distance around a shape. Remember that area is the size of the surface of a shape, and that area is measured in square units. Remember that volume is the amount of 3D space which a shape occupies, and that volume is measured in cubic units.
How do you find area?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Is length a volume?
Length is the measurement of the extent of something along its greatest dimension. Volume is the amount of space occupied by a sample of matter. Volume can be determined by knowing the length of each side of the item.
Which volume is the smallest?
One microliter
How a burette is used to dispense a volume of liquid?
It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end. On a liquid burette, the stopcock is at the bottom, and the precise volume of the liquid dispensed can be determined by reading the graduations marked on the glass tube at the liquid level before and after dispensing it.
How does a burette look like?
A burette is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock’s outlet.
How precisely can you read a Buret?
A 50 mL buret can be read to ±0.01 mL, but in order to be able to interpolate to the last digit, the perpendicular line of sight must be followed with meticulous care.
