Answer:
What's the question?
Step-by-step explanation:
Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm
Y=k/x
1.6=k/0.5
K=0.8
Y=0.8/x
3.2=0.8/x
X=0.8/3.2
X=0.25
Hope this helps
Answer:
40
Step-by-step explanation:
f(n) = 5 + (n - 1)(5)
f(n) = 5 + 5n - 5
f(n) = 5n
n = 8
5(8) = 40
