Rectangle & Square

Finding the volume in a rectangle is simple.
Multiply the short side by the long side then multiply the depth.
No fancy tricks, just length times width times depth times factor.
Its the same with the square area, multiply the two sides then the factor.

Rectangle = Length x Width x Depth
Square = Length x Width x Depth
The factor used in the calculations is 2 and all values are rounded up to the nearest full bag.

Length = Width = Depth =

Circles

If the circle is 20 feet across take half of that (10) and multiply it by its self then multiply it by the depth, ensuring that you do it in the same units.

Circle's Volume = (3.14 x Radius²) x depth The factor used in the calculations is 2 and all values are rounded up to the nearest full bag.

Radius = Depth =

Triangles

Right-Angled Triangles are kind of like rectangles, taking calculations form a right angle multiply a x b then divide by 2 hen multiply by the depth.
This only works with RIGHT-ANGLED triangles.
That means that one corner has to be square (90º).
Triangle's Volume = ((a x b) ÷ 2) x depth.
To convert to the number of bags multiply by the factor. The factor used in the calculations is 2 and all values are rounded up to the nearest full bag.

A =   B =   Depth =
