Question 183609: A 2" square is cut from each corner of a rectangler piece of sheet metal. The metal is bent up to form a box with no top. The length of the box is 5" more than the width. The volume of the box is 168 in^3.
Find: the surface area of the box?
note: Define var. define other quantities as needed, write a quadratic equation in one var., solve. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let in = the width of the box
Let in3 = volume of the box
given:
length = in
height = in in3
------------------------
Solve using quadratic formula Can't use a negative value here
and
If I flatten out the box and put the 4 square cut-outs from
the corners back, then 4 inches gets added to the width
and 4 inches to the length. is the width of flattened box is the length of the flattened box
Area =
Area =
Area = in2
