The answer is A is this geometry?
The answer should be<span> 4. Because in each cube you take from one corner,it seems like you lost 3 square shaped area but when you remove the cube, there occurs the hidden 3 square shaped area under that cube. So the surface area doesn't change. You should try to imagine the cube, it may help. </span>
Answer:
12
Step-by-step explanation:
The angle equals 90 degrees so (8*12-6) would equal 90
hopefully i helped
Let the third side be x :
( 3√5 )^2 = 6^2 + x^2
45 = 36 + x^2
x^2 = 45 - 36
x^2 = 9
x = 3
8/20as well，since the number of green beads and yellow beads is the same，so equal probability
