What is the error - the volume of a triangular prism with height 10 cm and base area 25 cm is 250 cm squared?
You have to calculate the volume as (1/3) times (base area) times (height). You forgot the factor 1/3.

How can you calculate standard error in volume?
The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
How do you work out the square root of 8?
Trial and error. You know that the answer will be between 2 and 3, closer to 3. 2.8 squared = 7.84 2.82 squared = 7.95 2.828 squared = 7.99 2.8284 squared = 7.999 which is close enough for me.
What is absolute error formula?
Absolute and Relative Error Absolute and relative error are two types of error with which every experimental scientist should be familiar. The differences are important. Absolute Error: Absolute error is the amount of physical error in a measurement, period. Let's say a meter stick is used to measure a given distance. The error is rather hastily made, but it is good to ±1mm. This is the absolute error of the measurement. That is, absolute error = ±1mm (0.001m). In terms common to Error Propagation absolute error = Δx where x is any variable. Relative Error: Relative error gives an indication of how good a measurement is relative to the size of the thing being measured. Let's say that two students measure two objects with a meter stick. One student measures the height of a room and gets a value of 3.215 meters ±1mm (0.001m). Another student measures the height of a small cylinder and measures 0.075 meters ±1mm (0.001m). Clearly, the overall accuracy of the ceiling height is much better than that of the 7.5 cm cylinder. The comparative accuracy of these measurements can be determined by looking at their relative errors. relative error = absolute error value of thing measured or in terms common to Error Propagation relative error = Δx x where x is any variable. Now, in our example, relative errorceiling height = 0.001m 3.125m •100 = 0.0003% relativeerrorcylinder height = 0.001m 0.075m •100 = 0.01% Clearly, the relative error in the ceiling height is considerably smaller than the relative error in the cylinder height even though the amount of absolute error is the same in each case.
What is the square root of co-efficient of non determination is called?
Standard error times squared degrees of freedom.

What would happen if width length and height were incorrectly measured for the purpose of volume?
Then the calculated volume would also be wrong, in proportion to the error in measurement.
How can you calculate standard error in volume?
The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
How volume is measured?
By multiplying the height the width and the length. In chemistry, you would often measure volume using a burette, pipette, graduated cylinder and beaker (in order from lowest to highest error in reading)
Is a higher or lower root mean squared error better?
A lower.
A box with a square base has its height twice its width.If the width of the box is 8.5 inches with a possible error of 0.3 inches find the possible error in the volume of the box.?
Area of base lies between 8.2 x 8.2 and 8.8 x 8.8 ie between 67.24 and 77.44. Height between 16.4 and 17.6 so volume lies between 16.4 x 67.24 and 17.6 x 77.44 ie between and 1102.736 and 1362.944 cuinches, a possible error of 260 and a bit cuinches

What if your true height is 70.0 inches (5 ' 10 '') but a nurse in your doctor's office measures your height as 69.9 inches. what is the absolute error?
The absolute error is 0.1 inch.
How do you calculate mean squared error?
The Mean Squared Error (MSE) is a measure of how close a fitted line is to data points. For every data point, you take the distance vertically from the point to the corresponding y value on the curve fit, this is known as the error, and square the value. Next you add up all those values for all data points, and divide by the number of points. The reason for squaring is so negative values do not cancel positive values. The smaller the Mean Squared Error, the closer the fit is to the data. The MSE has the units squared of whatever is plotted on the vertical axis.
Why air dried sample is used in sieves analysis?
to remove the air bubble, which are made error in volume. S.Kailash
An error in which would result in a greater error in the density of the cylinder mass radius or length?
An error in measuring the radius of the cylinder would result in a greater error in the calculation of density compared to an error in measuring the length. This is because density is proportional to the square of the radius in the formula for the volume of a cylinder (V = πr^2h), so any error in radius measurement would have a squared effect on the final density calculation.
What dimension needs to be more precise in calculating the volume of a cylinder?
An error in measuring the radius (or diameter) of the cylinder has a greater effect on the accuracy of the volume calculation than an error in measuring the cylinder's length, since the volume is proportional to the square of the radius.
