Answer: 64 in.^3

Step-by-step explanation:

one side of the length of the cube is x.

Therefore the area is x^2

volumes is x^3

volume is 4 times the area of one face

v (X^3) = 4 * x^2

to make the equation equal x has to be 4.

X^3 = 4 * x^2

which is, 4^3 = 4 * 4^2 (4*4*4 = 4*4*4)

therefore the v is 64in.^3

Jacob and Ali want to run from one corner of a football field to the opposite corner. The rectangular football field is 50 yards
svet-max [94.6K]

Answer:

Jacob ran 40 yards more than Ali.

Step-by-step explanation:

Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards

Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob = (\text{Length+width})

Distance run by Jacob = 50 + 120 = 170 yards

Ali runs through the middle of the field diagonally on a straight line.

Therefore, distance covered by Ali = \sqrt{\text{length}^{2}+\text{width}^{2}}

= \sqrt{(50)^{2}+(120)^{2}}

= \sqrt{2500+14400}

= \sqrt{16900}

= 130 yards

Now difference between the distance covered by Jacob and Ali

= 170 - 130

= 40 yards

Therefore, Jacob ran 40 yards more than Ali.
