Question

A solid gold cube with edge of 2" is melted down and recast as a cone with a 3" radius base.

Find the height of the cone.

Answer 1

its simple, the volumes would be the same for cube its s^3 = 2^3 = 8


and for cone its (1/3)(pi)(r^2)(h) = 8

(pi)(3^2)(h)=24

pi(h)=24/9=8/3

h= (8/3)3.14 I hope its correct

Answer 2

thnks it is
