1) A cube has a side length of 7 in.


What is the volume of the cube?
MY ANSWER:21

2) A cube has a side length of 14 meters. What is the volume of the cube?

A.
2744 m3

B.
1176 m3

C.
168 m3

D.
42 m3

MY ANSWER: D

Both answers are wrong.

Cube
Solve for volume
V=a^3

Sorry I did it wrong

1) 343
2) A

Now you're right.

Thank you Ms.Sue

You're welcome, Rochelle.

A plane intersects this rectangular prism perpendicular to the prism’s base.


Which two-dimensional figure is the cross section that results from the intersection of the plane and the prism?

A.

The plane intersected a rectangular prism parallel to its base.

B.
The plane intersected a rectangular pyramid perpendicular to the pyramid’s base and through its vertex.

C.
The plane intersected a rectangular pyramid perpendicular to the pyramid’s base and not through its vertex.

D.
The plane intersected a rectangular pyramid perpendicular to its base.

I would say C

Nevermind it is A

To find the volume of a cube, you need to know the side length. The formula for the volume of a cube is side length cubed.

In question 1, the cube has a side length of 7 in. To find the volume, you would calculate 7^3 = 343 cubic inches. Therefore, the correct answer is not 21, but rather 343.

In question 2, the cube has a side length of 14 meters. To find the volume, you would calculate 14^3 = 2744 cubic meters. As you correctly stated, the answer is D - 2744 m3.

Remember, to calculate the volume of a cube, you need to raise the side length to the power of 3.
