Pl help me!! What would be the volume of the box if it’s factor is scaled down by 1/10? The volume is 130 inches

let

x> the length side of the box

y> the width side of the box

we know that

h=3 in

V=390 in³

volume of the box=x*y*3> 390=x*y*3> x*y=130> equation 1

x=3+y> equation 2

substitute 2 in 1

[3+y]*y=130> y²+3y=130> y²+3y-130=0

using a graph tool> to resolve the second order equation

see the attached figure

the solution is

y=10 in

x=3+y> x=3+10> x=13 in

the answer is

the width is 10 in

1. perpendicular

2. parallel

3. perpendicular
