Answer:
20160 pounds
Step-by-step explanation:
20 * 15 * 12 = 3600 feet^3 = Volume
3600 feet^3 * 5.6 pounds = 20160 lbs
Explanation:
The question requires that we round the given number to Ten-thousand
To do so, we will have to write the place values of the numbers first
Next, we find the digits before the Ten-thousand digits and then approximate the value
One of the principles to use is that
numbers from 0 to 4 are rounded to 0
while numbers from 5 to 9 are rounded to 1
In our case, The thousand digit is 0, so we round down to 0, then we add to the Ten-thousand digits and convert each of the numbers before the Ten-thousand digits to 0
Thus, we will have

Hence, the answer is 1,370,000
s = side length of square
L = s-6 = width of rectangle (shorter side of rectangle)
W = s+1 = length of rectangle (longer side of rectangle)
multiply the length and width to get the area A
A = L*W
A = ( L ) * ( W )
A = (s-6)*(s+1) .............. substitution
A = s^2 + s - 6s - 6 ... use the FOIL rule
A = s^2 - 5s - 6 ......... combine like terms
<h3>Final Answer: s^2 - 5s - 6</h3>
