The volume of a box is the length x with x height. Because it is a cube all the sides are the same size, and it’s has three dimensions. That means you can calculate the length of one side by picking the root^3 (I don’t know what it is in English it is a square root with a 3 in the upper left corner) of 512. That gives you 8, so the sides are 8 inches Kong’s
First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse =
<span>
<span>
<span>
15.62 feet
Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
</span></span></span>hypotenuse² =
15.62² + 8²
hypotenuse² =
244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.
Given :-
- The price of a telephone reduced form Rs 3500 to Rs 3200.
To Find :-
- Percentage decrease from it's original price .
Solution :-
Here the initial cost is Rs 3500 and the new cost is Rs 3200. So the decrease in its price is ,
→ Decrease = Rs 3500 - Rs 3200
→ Decrease = Rs 300
Now we may find the % change in its price by ,
→ Decrease in cost/Initial cost * 100 %
→ Rs 300 /Rs 3500 * 100 %
→ 8.57%
<u>Hence</u><u> </u><u>the </u><u>price</u><u> </u><u>is </u><u>decreased</u><u> </u><u>by </u><u>8</u><u>.</u><u>5</u><u>7</u><u>%</u><u> </u><u>.</u>
I hope this helps.
