Answer:

Step-by-step explanation:
Given the expression: 

We can re-write the answer as:

The answer is irrational because the sum of a rational number and irrational number is an irrational number.
<u>The correct option is B.</u>
The volume of the box will be equal to V= 288 cubic inches.
<h3>What is volume?</h3>
Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the Cuboid.
The given parameters of the box are:-
12 inches long
6 inches wide
4 inches tall
So the volume of the box will be:-
V = L x W x H
V = 12 x 6 x 4
V = 288 square inches
Therefore the volume of the box will be equal to V= 288 cubic inches.

Fact #1:
A cube has six faces.
Fact #2:
Every one of them has the same area.
Fact #3:
The surface area of each face is (the length of the cube's side)²
Now that I look at this one more carefully, the only thing you need to know
to solve it is Fact #3. (But you can keep the others and save them for later.)
The surface area of each face is (the length of the cube's side)²
64 is the (length of the cube's side)²
Can you find a number that gives you 64 when you multiply it by itself ?
That's the length of the cube's side.
