A shipping box has to have specific dimensions to hold an item. The volume must be 7500 cubic inches. The length must be 5 times
Gennadij [26K]

The dimension of the box is 50in by 10in by 15in

<h3>How to calculate the volume of a figure</h3>

The volume of an object is the quantity of substance it contains.

The formula for calculating the volume of the box is expressed as:

V = lwh

where:

  • l is the length
  • w is the width
  • h is the height

Given the following parameters

length = 5w
height = w + 5

Substiute

7500 = 5w(w)(w+5)
7500 = 5w²(w+5)
1500 = w³+5w²
w³+5w² - 1500 = 0

<u>Factorize to determine the width</u>

On factorizing, the width of the box is 10 inches

Recall that:

l = 5w
l = 5(10)

l = 50inches

<u>Get the height</u>

h = w + 5
h = 10 + 5
h = 15inches

Hence the dimension of the box is 50in by 10in by 15in

Firlakuza [10]
David Howell was shopping for a leather jacket and found one on the dept. store that costs 395 dollars.
Now, he learned that an inflation rate of 4.5% has occurred since the jacket was originally priced.
=> 395 dollars * .045 = 17.775
=> 395 dollars - 17.775  = 377.23 is the original price of the jacket.
