Answer:
Price of paint = Rs 16,640
Step-by-step explanation:
As 3 dimensions are given so the third one must be for ceiling.
So in this case, we can find area as follows:
Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1
Lets say:
Length = 8m
Width = 6m
Height = 4m
So putting value in eq1 we get:
Area = 2(8*6) + 2(8*4) + 2(4*6)
Area = 2(48) + 2(32)+ 2(24)
Area =96 + 64 + 48
Area = 208 sq. m
Now for calculating price:
Price of paint = 208 * 80
Price of paint = Rs 16,640
I hope it will help you!

Answer:
The third option (C) Yes, because there is enough water in the cooler for about 81 cups total.Step-by-step explanation:
The numbers of new CDs is 30 and the old CDs is 21.
To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.
<h3>System of Equations</h3>
This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;
- Let n represents numbers of new CDs
- Let u represents numbers of old CDs
The equations can be represented as

Let's take equation (i)
Making n the subject of formula

we can put equation (iii) into equation (ii)

Let's put the value of u into equation (i)

From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.
