if two pyramids are similar and the ratio between the lengths of their edges is 2;7 what is the ratio of their volumes? ...?
jok3333 [9.3K]
<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} \\<span>
</span><span><span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> </span></span></span></span></span></span></span></span></span> </span></span> </span>
V₁ and V₂ - volumes of pyramids,
l₁ and <span>l</span>₂ - the edges of pyramids.
<span>
</span>\frac{V_1}{V_2} =( \frac{l_1}{l_2} )^{3} \\ \frac{V_1}{V_2} =( \frac{2}{7} )^{3} \\ \frac{V_1}{V_2} = \frac{2^{3}}{7^{3}} \\ \frac{V_1}{V_2} = \frac{8}{343} \\<span>

What is 10 = 0.860(7) + 3.302
Vesnalui [34]

Hey there!

0.860(17) + 3.302 = 10

= 0.86(17) + 3.302

= 14.62 + 3.302

= 17.922


Thus, your answer is: FALSE because

17.922 ≠ 10


Good luck on your assignment & enjoy your day!
