The volume of pyramid B is 1.9 times bigger than pyramid A volume.
If a is the length of a base edge and h is the length of the height
then the volume is a³h/3
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.
