<PRE><B>Question 329678</B>
The volume of two similar kettles are 2160 cm^3 and 640 cm^3
.what is the ratio of their bases?.
if the smallest kettle has a height of 16 cm, what is the height of the larger kettle?
:
Ratio of the dimensions from the volumes: {{{3sqrt(2169)/3sqrt(640)}}} = 1.5
:
&quot;if the smallest kettle has a height of 16 cm, what is the height of the larger kettle&quot;
1.5 * 16 = 24 cm 
:
:
&quot;what is the ratio of their bases?&quot;
I assume they want the area of the bases
:
640/16 = 40 sq/cm, the small kettle base
and
2160/24 = 90 sq/cm, the large kettle base
:
Ratio small to large: 4:9
