I think that it is 2 602/1000
To find the incompleted portion of the test, convert the decimal to a percentage by moving the decimal two places to the right. .7 as a percentage is 70%. subtract 70% from 100%, giving you 30%. Juan has not completed 30% of his test, or 5 questions.
<span>The answer is 8:343.
</span>We can use Galileo's square cube law to calculate the ratio between two similar pyramids. The law is used to describe the change of the area or the volume of the shape when their dimensions increase or decrease:
![\frac{V_1}{V_2} =( \frac{l_1}{l_2} )^{3} \\](https://tex.z-dn.net/?f=%20%5Cfrac%7BV_1%7D%7BV_2%7D%20%3D%28%20%5Cfrac%7Bl_1%7D%7Bl_2%7D%20%29%5E%7B3%7D%20%5C%5C%20)

V₁ and V₂ - volumes of pyramids,
l₁ and <span>l</span>₂ - the edges of pyramids.
