Answer 1

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
