10 times 0.84 is 8.4 or 8.40 is completely fine as well.
Solution -
The sphere is centered in the cube, so diameter of the sphere is equal to the side of the cube. Hence ,the radius of the sphere is half of the length of the side.
If the length of side of the cibe = a , then radius of the sphere is 
Volume of the cube = a³, volume of the sphere =
π(radius)³ =
π(
)³
volume of the cube outside the sphere = volume of the cube - volume of the sphere
=
π(
)³
= 
=a³(1 -
)
Simplifying
p + -4 = (-9) + p
Reorder the terms:
-4 + p = (-9) + p
-4 + p = -9 + p
Add '-1p' to each side of the equation.
-4 + p + -1p = -9 + p + -1p
Combine like terms: p + -1p = 0
-4 + 0 = -9 + p + -1p
-4 = -9 + p + -1p
Combine like terms: p + -1p = 0
-4 = -9 + 0
-4 = -9
Solving
-4 = -9
Unit rate the the price for one thing, so we'll have to find the price for one ounce.

Just follow it:

It cost $.50 for one ounce.
