Answer is 512 cu.ft.
Volume of a cube is length x width x height
So 8 x 8 x 8 = 512
Answer:
5.66
Step-by-step explanation:
The Square Root of 8 = 2.82842712475.
So, now we times it by two.
2 * 2.82842712475 = 5.65685424949
So, if you round it to the nearest hundredth it's 5.66.
You multiply both equations by a factor to get them to have the same X coefficient, the first by 5 and the second by 2, you get 10x-15y=5 and 10x+8y=28. Then you subtract the equations to get 23y=23, y=1, plug y into first equaition, x=2. Answer is (2,1)
The length of BB' is 5.39 units.
