A rectangular piece of sheet metal has a length that is 8 in. Less than twice the width. A square piece 4 in. On a side is cut from each corner. The sides are then turned up to form an uncovered box of volume 2048 in.3 Find the length and width of the original piece of metal.

Answer:

Width = 24 inches

Length = 40 inches

Step-by-step explanation:

Let the width of the original piece of metal = [tex]x[/tex] inches

As per question,

Length of the original piece of metal = [tex]2x-8[/tex] inches

Square boxes of each side 4 inches is cut from each corner.

Therefore, height of the box = 4 inches

Width of the box = [tex]x-8[/tex] inches

Length of the box = [tex]2x-16[/tex] inches

Volume of a cuboid is given as:

[tex]Volume = Length \times Width \times Height[/tex]

Putting all the values:

[tex]2048 = 4 (x-8)(2x-16)\\\Rightarrow 256 = (x-8)^2\\\Rightarrow 16 = x-8\\\Rightarrow x =24\ inches[/tex]

Therefore, the width of original piece of metal = 24 inches

The length of original piece of metal = 2 [tex]\times[/tex] 24 - 8 = 40 inches
