What is the surface area of a square prism with sides that measure 8 units?
V125BC [204]

Answer:

<em>The surface area of square prism = 384 units squared</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given the square prism side 'a' = 8 units</em>

<em>The surface area of square prism = 2 a² + 4 a h</em>

Given square prism length , width and height also equal identical sides

The surface area of square prism = 2 a² + 4 a h

                                                        = 2(8)² + 4 (8)(8)

                                                        = 2(64) + 4(64)

                                                       = 384 units squared

<u><em>Final answer</em></u>:-

<em>The surface area of square prism = 384 units squared</em>

The price of a sweater was reduced from $20 to $12.By what percentage was the price of the sweater reduced?
Katen [24]

The price of the sweater was reduced by 40%

Step-by-step explanation:

Step 1; Cost before reduction was $20. The cost after reduction was 12$. Cost reduced= cost before reduction - cost after reduction

Cost reduced= $20 - $12 = $8

Step 2; We must find how much of the cost was reduced from the initial cost i.e. how much $8 is to $20. To do this we must convert it into a percentage. We divide the $8 with the $20 to get a value. This value must be multiplied with a 100 to be converted into a percentage.

Cost by which sweater was reduced=  \frac{8}{20}* 100 = 0.4 * 100 = 40

So the price of the sweater was reduced from $20 to $8 which equates to a reduction in 40%.
