Q. Two similar solids have a scale factor of 4. If the smaller one has a surface area of 10 ft2, what is the surface area of the larger one?
Q. A cylinder has a radius of 1 and a height of 4. If another cylinder is 3 times larger, what is the volume of the larger cylinder?
Q. Which of the following is NOT true about ordered triples?
They define the location of a point in 3D space
They consist of three numbers representing the w, x, and y axes
They exist in the 3D coordinate system
An example of one is (0, 0, 0)
All of the above are true
Q. If your car can get you from A to B, find the distance between A (-4, 9, 5) and B (3, 1, -1). Make sure to fill up the tank first though.
Q. A rectangular prism has vertices at (0, 0, 0) and (3, 2, 5). All of the following are vertices of this prism EXCEPT
(0, 2, 5)
(3, 0, 0)
(3, 2, 0)

Q. Find the volume of a triangular prism with vertices at A (0, 0, 0), B (5, 0, 0), C (3, 2, 0), D (0, 0, 7), E (5, 0, 7), and F (3, 2, 7). A drawing would probably be helpful.
