Answer:
300%
Step-by-step explanation:
S = ab
S1 = 2a × 2b
S1 = 4ab
S1 = 400%ab
=>The area is increased by 300%
The formula for volume (V) is <em>l * w * h</em>, where <em>l</em> is length, <em>w</em> is width, and <em>h</em> is height. So in a sense, we have already solved the first part of this problem!
V = 10 * 8 * 3
Now, all we have to do is complete this equation to find the volume.
10 * 8 = 80
80 * 3 = 240
The volume of Jose's box for baseball cards is 240 cubic inches.

Multiply 7 times 50 and 7 times 6 then add them
ex: [(7 X 50) + (7 X 6)]
Multiply all terms by 2 to get rid of fractions
2x+10=28-x
Add x to both sides
3x+10=28
Subtract 10 from both sides
3x=18
Divide both sides by 3
x=6
Final answer: x=6
Get as close to the perfect square, which you should have memorized. then divide the number by the perfect square. average the answers (perfect square and quotient) by adding them and diving by 2
