And solving we got:



Step-by-step explanation:
For this case we can define the following notation:
represent the width
And we want a maximum error of 0.0003 so we can set up the following equation:

And solving we got:

Answer:
<u>140 in^2</u>
Step-by-step explanation:
Finding the volume
Length = 4
Width = 7
Height = 5
V = w h l = 7 x 5 x 4 = 140 in^2
Perimeter of a triangle =sum of all sides
=2x-7+5x-3+2x-2
=2x+5x+2x-7-3-2
=9x-12
