Answer:
486cm^2
Step-by-step explanation:
cube volume: 729cm^3
cube faces count: 6
How you calculate square area:
s(cm) * s(cm) or just s^2(cm^2)
s = side length
If you want to find out the side length of a cube by its volume. Then simply just remove the ^3 by taking the cubic root (also written ^(1/3))
729^(1/3) = 9
then just calculate the area like i showed earlier:
(9cm)^2 = 81cm^2
But that is only one side of a cube's 6 sides, so multiply by 6:
81cm^2 * 6 = 486cm^2
Hope i could help :D
Dont be scared to ask me questions..
Answer: y = 91
Step-by-step explanation:
y = -7(-13)
y = -7 x -13
y = 91
Answer:
i think it is 234 i am not sure
Step-by-step explanation:
Answer:
131
Step-by-step explanation:
Using proportion,
If Out of 550 calculators = 6 are defective,
Then out of 12000 calculators = ? are defective
= 21.8 * 6
= 130.8 ≈ 131
∴ Approximately 131 calculators are defective
M=123 degrees g=81 degrees f=99 degrees k=57 degrees q=81 degrees s=42 degrees h=123 degrees p=99 degrees r=57 degrees v=123 degrees u=57 degrees
