I’m not sure if it’s add or multiple the sides of each I don’t know if this even helped lol
Volume of a cube = (edge)^3
In this problem,
Volume = 216in^2
Edge = ?
Let's plug our values into the formula above.
216in^3 = (edge)^3
Take the cbrt of both sides.
6in = edge
The length of each edge = 6in
Answer:

Step-by-step explanation:
Given


Required

This is calculated as:

Since, it is a probability with replacement, we have:

So, we have:


Answer:
29.187
Step-by-step explanation:
Cos38°= base/hypotenuse
Cos38°= 23/w
w= 23/Cos38°
w= 23/0.788
w= 29.187
Hope it helps :-)
