The picture is kind of blurry and I can’t make out the formulas. /:
Answer:
Step-by-step explanation:
V of a cube is s^3
V = 512
s = cube root of (V)
s = cube root of 512 cm^3
s = 8
The area of one face of the cube is s^2
s = 8
Area 1 face = 8^2
Area of 1 face = 64 cm^2
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:

Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get



Now,



Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.
Graph the equations and locate the intersection.
