find the volume of cubical box . if the cost of painting of outer surface is rs 1440 at the rate rs 15 per mcube

bearhunter [10]

Surface of a cubical box=6(side²)

1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface ⇒surface=cost of painting/rate

Data:
Rate=$15/m²
cost of painting=$1440

Surface=$1440/($15/m²)=96 m²

2)We find out the length of the side:

Surface of a cubical box=6(side²)

Data:
Surface of a cubical box=96 m2

Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m

3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³

Answer: the volume of this cubical box would be 64 m³.

A book has 12 chapters. The mean length of the chapters is 40 pages. How many total pages are there in the 12 chapters?

amm1812

Answer:

480

Step-by-step explanation:

Important Information:

A Book Has 12 Chapters.

The Mean length of the chapters is 40 pages.

Question to Answer:

How many total pages are there in the 12 chapters?

Explanation/Solution:

Let's assume that the total number of pages in the book is "x" pages.

To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.

$\frac{x}{12}$ =40

Multiply both sides by 12...

x = 480

Hence, The total number of pages in the 12 chapters is 480.
