Use Pythagorean theorem
x^2 + x^2 = 2x^2
sqrt(2x^2)=x sqrt(2)
250 laps total. I used cross multiplication to solve it
Volume of a rectangular prism = 40 cubic feet.
Volume of a rectangular prism = length * width * height
width = x
length = 1 foot greater than its width = x + 1
height = 2 feet less than its width = x - 2
l * w * h = 40 ft³
(x+1) * x * (x -2) = 40
(x² + x)(x-2)
x³ - 2x² + x² + 2x = 40
x³ - x² + 2x - 40 = 0
solve for the value of x. I used the calculator to get the volume.
width = x = 4
length = x + 1 = 4 + 1 = 5
height = x - 2 = 4 - 2 = 2
V = 4 * 5 * 2
V = 20 * 2
V = 40 ft³
