To find the surface are youd have to multiply 6 1/2 by 6, because a cube has 6 total sides. so the answer would be 6•6.5 which equals 39
Answer:
Interest = $93.205
Explanation:
Interest can be calculated as follows:
I = Prt
where:
I is the interest we want to canlculate
P is the principle amount = $1400
r is the interest rate in decimal = 9% = 0.09
t is the time in years = 270/365
Substitute with the givens in the above equation to get the value of the interest as follows:
I = 1400 * 0.09 * (270/365)
I = $93.205
Hope this helps :)

Answer:
(a) There is $1740.88 in Mary's account after 2 years
(b) The interest earned on Mary's investment after 2 years is $40.88
Step-by-step explanation:
Let us revise the rule of the compound interest
→
, where
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
∵ She invested $1700
∴ P = 1700
∵ The rate is 1.19%
∴ r = 1.19/100 = 0.0119
∵ It is compounded quarterly
∴ n = 4
∵ She decided to invest her money for 2 years
∴ t = 2
Let us substitute these values in the rule above to find her new amount of money in her account
→ 
→ 
→
dollars
Round it to the nearest cent → means 2 decimal places
→ A = $1740.88
(a) There is $1740.88 in Mary's account after 2 years
The interest amount is the difference between the new amount and the initial amount

∵ P = 1700
∵ A = 1740.88
∴ 
∴ I = $40.88
(b) The interest earned on Mary's investment after 2 years is $40.88
