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>

Answer:
Step-by-step explanation:
area of rectangle=length×width
=(x²+6x+3)×(3x²+4x-2)
=3x^4+(4+18)x³+(-2+24+9)x²+(-12+12)x-6
=3x^4+22x³+31x²-6
