3 because length times width = area right. so 3x3=9.
100+60+x x=? to figure out the problem, you look at hundredth digit. 100 but wait. 100+60 in expanded form is 160. 160x to figure out x, you need to subtract 2 from 60. Which is 58. Unless it's 2-6. 2-6=4. in expanded form, the answer is 100+60+4 but we speak numbers so in the number form, it would be: 164 so x=4
False
Multiples of 4:
4,8,12,16,20,24,28,32,36
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
