Answer:
Step-by-step explanation:
A cube is made up of 6 squares
One square has 4 edges of equal length
The area of one face is Area = s^2
Therefore the surface area is 6 * s^2
The area of this cube is 6 * 5 * 5 = 150 units.
Dont see any answer choices... but Volume= L*W*H
A cube, the sides are equal. So 13^3 or 13*13*13 = the volume of the cube. Then work your way to the rectangular prism.

Answer:
interest rate = 2.9%
Step-by-step explanation:
the principal is $25,000, the interest is $10,875
Number of years = 15
We use simple interest formula
I = P*r*t
Where I is the interest amount=10,875
P is the principal amount= 25000
r is the interest rate = r
t is the number of years = 15
Plug in all the value in the formula
I = P*r*t
10875 = 25000 * r * 15
10875 = 375000 * r
Divide both sides by 375000
r=0.029
We always write rate of interest in percentage so we multiply by 100
0.029 * 100= 2.9%
So interest rate = 2.9%
