lara [203]
<h2>I'm kind of confused about what you are asking but wouldn't this | be the answer?                                                       V</h2>

Answer: 2 inches per minute

Step-by-step explanation:

This is a fraction equal to

0.14285714285714 inches ÷ 0.071428571428571 minutes

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.071428571428571

0.14285714285714 inches ÷ 0.071428571428571

<h3><u>                                                                                  </u></h3>

0.071428571428571 minutes ÷ 0.071428571428571

<h3>=  </h3>

2 inches

<h3><u>              </u></h3>

1 minute

<h3>=  </h3>

2 inches

<h3><u>             </u></h3>

minute

= 2 inches per minute

A shipping box is 12 inches by 18 inches by 16 inches the shipping box will be filled with smaller boxes each boxes each smaller
LenKa [72]

The number of small boxes that will fill the truck will be 144 boxes

The formula for calculating rectangular box is expressed as:

V = LWH

L is the length

W is the width

H is the height

For the large box

Volume = 12 * 18 * 16

Volume = 3,456 cubic inches

For the small box:

Volume of the small box = 3 * 2 * 4

Volume of the small box = 24 cubic inches

Number of small boxes that will fill the truck = 3456/24

Number of small boxes that will fill the truck = 144

Hence the number of small boxes that will fill the truck will be 144 boxes
