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

1-14, You're just dividing. Like #1, -14÷2=-7 (negative fourteen divided by two, equals negative seven). A positive and a positive make a positive, a negative and a positive make a negative, a negative and a negative, make a positive. The word problems your also dividing, for example, #15, -40÷4=-10. Use the numbers that are given to you.
