take x as the side of the cube.
surface area = 6a^2
= 6x^2
take 2x as the next cube
surface area = 6(2x)^2
= 6 x 4 x x^2
= 24x^2
cube two is 4 times more than cube 1 in surface area wise.
HOPW THIS HELPS AND PLEASE MARK ME AS BRAINLIEST.
The amount of elapsed time is 28 minutes since the difference between 6:35 and 7:03 is 28 minutes
Given :
Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.
To Find :
If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.
Solution :
Time taken to walk one mile uphill is :
Time taken to walk two mile on flat land( one on going and one or returning ) is :
Time taken to walk one mile downhill is :
Total time taken :
Therefore, time taken un 62 minutes.
Is that go math? So i can check
3.50 will be the tipe since if we divide we dont payed that much for the tip
