Answer:
She should cut each diagonal piece 10 ft long.
Step-by-step explanation:
The bottom face of the box is a rectangle 8 ft by 6 ft.
A diagonal of a rectangle divides the rectangle into two congruent right triangles. With a right triangle you can use the Pythagorean theorem.
a = length of rectangle = leg of right triangle
b = width of rectangle = other leg of right triangle
c = diagonal of rectangle = hypotenuse of right triangle
a^2 + b^2 = c^2
(8 ft)^2 + (6 ft)^2 = c^2
64 ft^2 + 36 ft^2 = c^2
c^2 = 100 ft^2
Take the square root of each side.
c = 10 ft
Answer: She should cut each diagonal piece 10 ft long.
