Glover · Answer 1

A) Scale factor of the smaller pyramid to the larger pyramid in simplest form:

6 m / 12 m = 1/2

b) Ratio of the areas of the bases of the smaller pyramid to the larger pyramid:

(1/2) ^2 = 1/4

c) Ratio of the volume of the smaller pyramid to the larger:

(1/2) ^3 = 1/8

d) Volume of the smaller pyramid:

(1/8) * 400 m^3 = 50 m^3
