What is the area surface of the cube with the given Edge length: s=15in?

A cube has 6 faces which are squares, if an edge have 15 in length so its the square side

Cube area = 6 . square areas

Ca = 6 . 15²

Ca = 6 . 225

Ca = 1350 in²

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
