<h3>G I V E N :</h3>
find the cost of the painting of a rectangular box of length 6m breadth 4m and height 3m at the rate of rs.25 per meter square
<h3>S O L U T I O N :</h3>
According to the question, first we need to get the T.S.A. or Total Surface Area of the cuboid then dividing it by ₹ 0.25 we can get the cost. After solving the concept will be more clear.
Let's start :
Here,
l represents length
b represents breadth
h represents height
Now, putting the values of all these we get
- T.S.A. = 2(6 × 4 + 4 × 3 + 3 × 6)
- T.S.A. = 2(24 + 12 + 18) m²
Now, we are given that cost of every square metre costs ₹ 0.25
So, for 108 m² it will cost = ₹ 108 × 0.25 = ₹ 27
<u>Hence, cost of painting the </u><u>rectang</u><u>ular box is ₹ 27</u>
Assuming that the pool is a perfect rectangular prism, then its volume, V, is given by
, where l is the length, w is the width, and h is the height. Manipulate this formula first to solve for length.
Divide both sides of the equation by w*h.
Now, plug in your values for volume, width, and height.
The answer is 120 ft.

Answer:
Not proportional.
Step-by-step explanation:
Given ratios:
To tell whether the ratios are proportional or not.
Solution:
In order to tell whether the given ratios are proportional or not, we will reduce the fractions to the simplest numbers by dividing the numerator and denominator by their greatest common factor and then comparing them. If they are equal then the ratios are proportional else not proportional.
So, the simplest form of can be calculated by dividing both by 2 as it is the G.C.F.
the simplest form of can be calculated by dividing both by 2 as it is the G.C.F.
Now, since , hence the ratios are not proportional.
