Question

which method is used to measure the volume of irregular solid? which is it principal behind this method ​

Answer 1

$\huge\red{answer}$

Keep in mind that the weight of the fill could expand the hole.

To estimate volume as surface area times average depth:

Surface area: Length x width x percent of rectangle occupied.

Average depth: Depth at each point on a grid mapped over the surface.

Surface measuring:

Use a drone to take a picture you can measure for the area percentage occupied.

Or use laser distance measuring devices to measure depths and widths.

Mount laser on a drone to measure many depths for calculating average depth.

OR: For volume, count the number of golf balls it takes to fill the pit.

Accuracy is to “nearest significant golf ball”.

Or, weigh sand used to fill pit. Use Quora to get the volume based on the weight.
