what is the ratio for the volumes of two similar pyramids, given that the ratio of thier edge lengths is 8:3

512:27

Step-by-step explanation:

We just cube the edge length ratio since a pyramid is a 3-dimensional figure and volume is 3-dimensional:

8:3 -> 8^3:3^3 -> 512:27

Therefore, the correct answer is 512:27

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
