An open box is to be made from a rectangular piece of tin by cutting 3-inch squares out of the corners and folding up the sides.

slava [35]

Answer:

Width of the Rectangular Tin=8 inch

Length of the Rectangular Tin= 16 inch

Step-by-step explanation:

Let the Width of the Rectangle=W

The length of the piece of tin is twice the width, Length = 2W

Since Squares of 3 inch are cut from all four corners of the rectangle

Length of the box = 2W-(3+3)=(2W-6) inches

Breadth of the Box = W-(3+3)=(W-6) inches

Height = 3 inches

Volume of the box = 60 cubic inches

Now, Volume of a cuboid=lbh

3(2W-6)(W-6)=60

Divide both sides by 3

(2W-6)(W-6)=20

Expanding the brackets

$(2W-6)(W-6)=20\\2W^2-12W-6W+36=20\\2W^2-18W+36-20=0\\2W^2-18W+16=0$

Factorizing

$2W^2-16W-2W+16=0\\2W(W-8)-2(W-8)=0\\(W-8)(2W-2)=0\\W-8=0 , 2W-2=0\\W=8, 1$

Since the Width cannot be less than 6,

Width of the Rectangular Tin=8 inch

Length= 2 X 8 = 16 inch

Identify the percent of change as an increase or a decrease. 9 points to 4 points

padilas [110]

Answer:

55.55% decrease

Step-by-step explanation:

$change\% = \frac{final \: point \: - initial \: point}{initial \: point \: value} \times 100$

In the question ,

Initial point value = 9

Final point value = 4

Change% = $\frac{4 - 9}{9} \times 100 = \frac{ - 5}{9} \times 100 = - 55.55\%$
