a box has a volume of 144 cubic centimeters. its width is 3 times its height, and its length is 3 more than 2 times its width. which equation can be used to calculate the height of this box?
Answers
Answer:
You divide 144 cubic inches by 8 inches (height) because you must use inverse operations on both sides of the equation to isolate the length x width. The inverse operation of multiplication is division, so the following is the application of division to the problem, broken down:
`144=l times w times 8`
`144 div 8=l times w times 8 div 8`
`18=l times w`

If the volume V = 144 cubic inches, and V = length*width*height,
then 144 cubic inches = length*width*8 inches
and length*width = 144/8 square inches = 18 square inches.
This means that the length and width can be any pair of numbers that has a product of 18.
Examples: 2*9, 1*18, 1/2*36, etc.
Keep in mind that the dimensions aren't necessarily whole numbers! There are actually infinitely many answers to this problem, so think of a way to describe the solution set in general terms.
I hope it will help you dear ❤️☺️
