It is 2142 square units.
63-29 = 34 neutrons 29 = atomic number of copper
Two stable isotopes: Cu(63) 69% occurrance and Cu(65) 31%They have (63-29)= 34 and (65-29)= 36 neutrons respectively.
.63 is also 63% or 63/100. (432 x .63) is the same as (63% of 432) which is the same as (432 x 63/100).
You will need 63 44cm x 44cm slabs to cover that area.
5ft 3in equates to 160.02cm
Area of a rectangle is length times width, therefore if the length is two feet longer than the width then the length is 9 and the width is 7, when they are multiplied you get 63
63
Let x = length; then x + 2 = width which is next odd integer x (x+2) = 63 x^2 + 2x - 63 = 0 (X-7)(x+9) = 0 X = 7 = length; width = 9
3 feet.
3 feet.
7cm x 9cm= 63 sq.cms
9x7 = 63 sq. ft
w x 2w = 63. 2w^2 = 63 w^2 = 31.5 w = sqrt 31.5 = 5.6125 so L = 11.225 which gives area of 63.0003, which is near enough for Wiki!
21 feet
63 X 9 X 7 = 3967 square cm.
Multiply width by length to get the area. The answer would be 6,300 square feet.
It is: 42+42+54+54+63+63 = 318 square cm
