Answer:
If you count the bottom layers that cant be seen, then it's 16 cubes.
Answer: F
Step-by-step explanation: 90/3.28 equals 27.4390244
Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12
If x=3, the perimeter is 16*3 +12 = 60 inches.
The answer would be positive 5
