Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge
Hence,
a³ = 8000
Take the cube root of both sides
a = 20
Hence,
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000
B is one.
A < C and D are rational
Im thinking about E. It looks like a recurring decimal at first sight but I think its irrational.
I believe it is twenty eight. Ten is two thirds of fifteen. Twenty eight is two thirds of forty two. But I'm just assuming tbh
Ok so we have 7:00 pm and she spends 12 more hours over.

So therefore, she spend 19 hours had her friends house! :D
Hope this helps!
