Answer:
No, it’s not possible according to calculations
Step-by-step explanation:
Mathematically, the area of a rectangular prism is;
2(wl + wh + lh)
Where w is the width, l is the length and h is the height;
Making the substitutions with values in the question
Surface area = 2(6x + 3x + 3(6))
Surface Area = 2(9x + 18) = 18x + 36 square inches
Volume of rectangular prism = l * w * h
Making substitutions;
V = x * 6 * 3 = 18x cubic inches
So therefore to get the value of x, we equate the surface area to the volume;
18x = 18x + 36
We can see that 18x will cancel out and will render our equation invalid
I think it is .05 but I am not 100% sure
If you divide 5 by 6 to turn it into a decimal, you get 0.83. All you have to do is find a numerator that you can divide by 8 to get a decimal less than 0.83.
So, 1/8, 2/8, 3/8, 4/8, 5/8, or 6/8 would work.
The first discounted price is given through the equation,
discounted price = ($3.45)(1 - 0.20) = $2.76
Then, due to the privilege of being a Coles-Myer discount card holder, another 7.5% discount is given. Such that the final price would be,
final price = ($2.76)(1 - 0.075) = $2.553
The total amount saved up is equal to,
$3.45 - $2.553 = $0.897
