Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge
Hence,
a³ = 8000
Take the cube root of both sides
a = 20
Hence,
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000
The answer is 9 pounds. how I arrived at it was to compute the following equation
$11.94 - $6.99 / .55
The Answer is
X=10
Explanation:
-288/5 or - 57.6 I used a calculator so I cannot solve step by step
Answer:
The first thing we need to do is find the area of the rectangle...
<em>l x w = A</em>
<em>7 x 8 = 56</em>
So the area of the first rectangle is 56m.
Now we multiply each dimension by 5...
<em>8 x 5 = 40</em>
<em>7 x 5 = 35</em>
So, now the width is 40m and the length is 35m,
Then, find the area of the new rectangle...
<em>35 x 40 = 1400</em>
The area of this rectangle is 1,400m!
<em>1,400 / 56 = 25</em>
So, by multiplying each dimension by 5, the area is now multiplied by 25!
