I believe it would be B. Because for one face of the cube you would need to calculate all four sides with however long the sides are.

Step-by-step explanation:
Take it in steps. First, find 7/9+6. Then we'll find 8+6/3, and, finally, we'll divide the two answers.
1:
7/9+6 = 7/15
2:
8+6/3 = 14/3
3:
or 
Then take that in chunks: 7/14 and 15/3.
7/14 = 1/2
15/3 = 5/1
Use those to rewrite it as 
.
1/5 = .2
2/3 ≈ .6667 so we'll keep writing it as 2/3
.2/2 = .1, so:
=
Answer:
180.6 cubic inches. (Nearest tenth is the same as 1 decimal place)
Step-by-step explanation:
The volume of a cylinder formula is:
V
=
π
r
2
h
The diameter is
10
inches, well half of the diameter is
5
inches which is the radius. Radius is half of the diameter.
If you want the diameter back, just double it.
5
+
5
=
10
.
So we can now plug the numbers into the formula.
V
=
π
(
5
2
)
(
2.3
)
V
=
π
(
25
)
(
2.3
)
(5 Squared =25)
V
=
57.5
π
But if you didn't want it in terms of
π
, so you multiply:
57.5
×
3.14
=180.55
but rounding that to the nearest tenth is the same as rounding to
1 decimal place so you get
180.6 cubic inches.
Oh my goodness . . .
What do you get when you multiply a number by itself ?
Do you get the square of the number ?
And what do you get when you square the square root of a number ?
Is it the number inside the square root ?
For just a second, let's take the quantity (4t - 3) and call it ' Q '.
Then the problem is to multiply
√Q times √Q .
Isn't that just ' Q ' ?
And is this enough help ?
