How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?

Pyramid B is 9 times bigger than pyramid A.

Step-by-step explanation:

The formula for determining the volume of a pyramid is expressed as

Volume = 1/3 × base area × height

Considering pyramid A,

base side length = 12 inches

Base area = 12² = 144 inches³

Height = 8 inches

Volume of pyramid A = 1/3 × 144 × 8 = 384 cubic inches

Considering pyramid B,

Volume of pyramid B= 3456 cubic inches

Therefore, the number of times by which pyramid B is bigger than pyramid A would be

3456/384 = 9
