Answer:
Option D. AC= 10 cm and CE= 5 cm
Step-by-step explanation:
From the given figure two triangles ΔABC and ΔADE are similar and two lines BC║DE.
From these similar triangles we know
Therefore
Or AC=
Now from pythagoras theorem
AE = √(AD²+ED²) = √(12²+9²) = √(144+81) =√225 = 15 cm
Since we know side AC =
=
= 10 cm
Therefore AC = 10 cm and AE = 15cm and CE = (15-10) = 5 cm
The formula for the volume of a cube is:
V = a^3
Plug in what we know:
125 = a^3
Cube the other side:
![a = \sqrt[3]{125}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%5B3%5D%7B125%7D%20)
V = a^3
Plug in what we know:
125 = a^3
Cube the other side:
