Answer:
500%
Step-by-step explanation:
We find the volume of pyramid A
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.
Volume = a² h/3
Where a = 9 in
h = 10 in
Volume = 9² × 10/3
Volume = 270 cubic inches
Pyramid B has a volume of 1,350 cubic inches.
Step 2
We compare both volumes
Pyramid A : Pyramid B
270: 1350
= 270/ 1350
= 1 /5
Hence, Pyramid B is 5 times bigthan ger pyramid A
In percent, it is the volume of Pyramid B 500% bigger than Pyramid A
