The last dot to the right would be the total distance.
So at 6 pm he had traveled 45 km.
The answer is 45.
You have to move the 8x over to the other side to get y by itself. and then divide the 4 from the y to the other side and y should equal y= 2x+5
Volume of the cube is given as 512 cm^3
We also know that
Volume of a cube = (side)^3
Then we can use this formula to find the size of each side of the cube very easily.
Let us assume the length of each side = x
Then
x^3 = 512
= 8
So the length of each side of the cube is 8 cm. I hope you have got the answer you were looking for. You can crosscheck the answer by multiplying 8 three times. You will get the result as 512. This is the only method to solve this problem.
