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

Step-by-step explanation:
Example of how to find the determinant of a 2×2 matrices is as shown;
![\left[\begin{array}{ccc}a&b\\c&d&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%26%5Cend%7Barray%7D%5Cright%5D)
= (a*d)-(b*c)
= ad - bc
Applying this to solve the given questions
1) (3*4) - (-3*-1)
= 12 - (3)
= 9
2) (-12*5)-(-1*12)
= -60 - (-12)
= -60+12
= -48
3) (0*4)-(-1*17)
= 0-(-17)
= 0+17
= 17
4) (8*-1)-(-4*-1)
= -8-(4)
= -8-4
= -12
5) (2*-1)-(2*-1)
= -2-(-2)
= -2+2
= 0
6) 1(1) - 0(0)
= 1 - 0
= 1
7√27 + 5√48
7 × 3√3 + 5√48
7 × 3√3 + 5 × 4√3
21√3 + 5 × 4√3
21√3 + 20√3
41√3 or 71.014
hope this helps, God bless!
