The volume of the cube is (8 x 8 x 8) = 8³ = <em>512 cubic inches</em> (exact)
We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.
The value of x is

5 feet. </span>
<span>you could have 3.15=100 times 0.0315, 10 times 0.315.</span>
<h3>Answer :- </h3>
<h3>Solution :- </h3>
- 2x + 42 = 90
- 2x = 90 - 42
- 2x = 48
- x = 48/2
- x = 24
