(7 points, a -rel.2.4) a packing company is doing an inventory of boxes. their most popular box is displayed below. use the formula for volume of a box, v = lwh. if the volume is 40f * t ^ 3 , find the value of x. then find the length and width of the box. state any extraneous solutions.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

it would open into a square depending on the type of envelope i’m not sure about the second part
