Answer:
480 Cubic inches
Step-by-step explanation:
Length:Breadth:Height = 5:4:3.
Let the Length of the Tin =5x
Breadth of the Tin =4x
Since the bottom area of the tin is 80 square inches.
Therefore:
Length of the Tin =5 X 2 =10 inches
Breadth of the Tin =4 X 2 =8 Inches
Height of the Tin =3 X 2=6 Inches
Volume of the Tin = Length X Breadth X Height
=10 X 8 X 6
=480 Cubic inches

1) x+y = 170
x-y = 26
2) Subtract the two equations from each other. Doing this you get 2y = 56.
So the value of y is 28. Then plug in the value of y into any of the two equations and solve for x.
x-28 = 26
x = 54
3) When writing solutions as an ordered pair, the x value always comes first followed by the y value. So it would be (54, 28).
A=Lw
P=2L+2w
216=Lw
W=216/L...substitute to Perimeter equation
60=2L+2(216/L)
60L=2L^2 + 432
2L^2-60L+432=0
2(L^2 - 30L + 216)=0
2(L-18)(L-12)=0
L=12, W=18 or L=18, W=12
