You look up the formula for the regular shape in a table of formulae, then apply such a formula. For example, if the regular shape is a rectangular block, you multiply length x width x height, if it is a cone you calculate (1/3)Bh (1/3 times the base area times the height), etc.

How do you find the volume of a 2D shape?
The answer is zero. A 2D shape has no volume.
What formula do we use to find the volume of regular objects?
The formula of volume
How do you calculate the surface-area-to-volume-ratio?
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
What are two ways to find the volume of an object?
if it is a regular shape, a box, prism, pyramid, cone, sphere, use a math formula. irregular shapes, use water displacement.
Area of an irregular shape?
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
