1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
<em>The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:</em>
<em></em>
Where L, B and H are the dimensions.
So,
<em>Hence, 1926 cm² of fabrics are needed to cover all surfaces.</em>
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
Where we taking 2 negative because temperature decreases.
Hence, it will take 7 hours for the temperature to reach -19° F.
