Volume of cube = side^3
= 15^3
= 3375
Volume of pyramid= length x width x height/3
= 15 x 15 x 9
= 675
Total volume = 3375 + 675
= 4050 cubic feet
Answer: 2/3 is a rational number
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b , that is , the numbers that can be expressed as a fraction.
It would be x = 18
You can get this by adding/subtracting common values. If you get all the x values on one side and all constants on the other side, you end up with
2x = 36
and all you have to do is divide by 2 to get x = 18.
