Ответ:
64 cm
Step-by-step explanation:
Given 2 similar figures with linear ratio = a : b, then
ratio of volumes = a³ : b³
Given
ratio of volume = 32 : 16384 then
ratio of heights =![\sqrt[3]{32}](/tpl/images/0538/1394/dae9e.png)
: ![\sqrt[3]{16384}](/tpl/images/0538/1394/00bce.png)
← values are not exact cubes
Using proportion then letting x be height of larger pyramid
8 =
( multiply both sides by 8 )
64 = x
That is vertical height is 64 cm
Ответ:
64cm
Step-by-step explanation:
(Side1/Side2)³ = Volume1/Volume2
(H/8)³ =
H³/256 = 16384/32
H³ = 262144
H = 64cm
