Standard 3 x 3 has a common total of 15, so multiplying each cell by 4 would create such a square:
16/36/08
12/20/28
32/04/24
If you want the cells to contain consecutive numbers then you have to use 16 - 24:
19/24/17
18/20/22
23/16/21
20 times 3 equals 60
None. There is no perfect square that, when doubled, equals 60.
-60
Algebraically, you're asking to solve for x: 5x - 60 = x4x - 60 = 04x = 60x = 15Let's test just to be sure:15*5 = 7575 - 60 = 15It works, so 15 is the magic number.

Well, darling, 20' x 60' equals 1200 square feet. So if you're looking to cover that area with some fabulous carpet or paint, you better make sure you have enough square footage to go around. Math may not be glamorous, but it sure does the trick when it comes to calculating space.

9x = 60x = 60/9 = 6 2/3 (or 6.67)
2100 square meters or 22,604.2 square feet.
4800, multiply 80 x 60. An easy way to solve this is to set up an equation. x/60 = 80. To solve for x, multiply both sides by 60. So then, its just 60 x 80 which is 4800
650 sq ft equals 60 m2.It is a modet apartment.
