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.
