A = 6 cm; B = 3 cm; C = 8 cm; D = 10 cm
The Surface area of the prism = 120 cm².
<h3>How to Find the Surface Area of Triangular Prism?</h3>
Surface area = Area of A + B + C + D
The side lengths are:
A = 6 cm
B = 3 cm
C = 8 cm
D = 10 cm
Surface area of the prism = 2(area of triangular face) + area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area of triangular face = 1/2(b)(h) = 1/2(8)(6) = 24 cm
Area of rectangle 1 = (length)(width) = (10)(3) = 30 cm²
Area of rectangle 2 = (length)(width) = (6)(3) = 18 cm²
Area of rectangle 3 = (length)(width) = (8)(3) = 24 cm²
Surface area of the prism = 2(24) + 30 + 18 + 24 = 120 cm².

Marian will pay $472.50 for the sound system if she pays the full amount in one year.
Step-by-step explanation:
Given,
Money borrowed for sound system = $450
Interest rate = 5%
Amount of interest = 5% of money borrowed
Amount of interest = 

If she pays the amount in one year;
Total amount to be paid = Money borrowed + Amount of interest
Total amount to be paid = $450 + $22.50 = $472.50
Marian will pay $472.50 for the sound system if she pays the full amount in one year.
