The volume of pyramid B is 1.9  times bigger than pyramid A volume.

Volume of a square pyramid

If a is the length of a base edge and h is the length of the height

then the volume is a³h/3

How to find volume of a pyramid A?

The base side length of pyramid A is 8 inches and the height of 9 inches.

The volume of a pyramid A is V

then

[tex]V=\frac{8^3\times9}{3}[/tex]

   = 512 × 3

   = 1536 in³

The volume of a pyramid A is 2,880 in³

So the times bigger is the volume of pyramid B than pyramid A is 2,880/1536 = 1.9.

Hence the volume of pyramid B is 1.9  times bigger than pyramid A.
