What is a rectangular prism?
A rectangular prism is a three-dimensional shape with a top and bottom (base) that are congruent rectangles and lateral (side) faces that are parallelograms.
100
The prism is cut vertically into two smaller triangular prisms. How does the volume of each smaller prism compare to the original prism?
Each smaller prism will have half the volume of the original prism.
100
The total surface area of any prism includes the lateral surface area and the base area. (True or False)
True

A cone has the same radius and height as a cylinder. What is the ratio of the volume of the cylinder to the volume of the cone?
The ratio is 3:1
(since the volume of a cone is one-third the volume of a cylinder with the same base and height).

Name three things from your life that are shaped like a cone, a sphere, and a cylinder?
(answers may vary)
Cone: Ice cream cone
Sphere: Basketball
Cylinder: Water bottle

Name three everyday objects that can be both filled and wrapped.
(answers may vary)
Burrito: Can be filled with ingredients and wrapped in a tortilla.
Gift box: Can be filled with a present and wrapped with gift paper.

What is a cylinder?
A cylinder is a three-dimensional geometric shape with two parallel, identical circular bases that are connected by a curved surface.

Can two prisms have different volumes but the same surface areas?
Yes, two prisms can have different volumes but the same surface area.
Prism 1:
Length: 4 units, Width: 2 units, Height: 6 units
Surface area = 88 square units
Prism 2:
Length: 3 units, Width: 4 units, Height: 32/7 units
Surface area = 88 square units

What two-dimensional shapes appear if you slice a cone as shown on each figure?
Triangle (left),
Trapezoid (middle), and
Circle (right)

What is the difference between surface area and volume?
Surface Area is the total area of all the faces or outer surfaces of a 3D object. It measures how much material would be needed to cover the outside of the object.
Volume: This is the amount of space inside a 3D object. It measures how much space the object occupies or can hold.

Suppose that a square prism has a base with sides of 3 cm and a volume of 81cm³.
What is the height of the prism?
9 cm

Which of the following are true in the case of a prism? (May have multiple answers)
A. A prism is a 3-dimensional solid object.
B. It has identical ends (polygonal) and flat faces.
C. Surface area of a Prism= 2 × (Base Area) + (Lateral surface area)
All of them.
(A, B, and C)

A cylinder is filled with water and has a height of 20 cm and a radius of 5 cm. If a solid sphere of radius 5 cm is dropped into the cylinder, how much will the water level rise?
(round to the nearest hundredth)
6.67 cm

What is the definition of pi (π)?
pi (π) The mathematical name for the ratio of a circle's circumference to its diameter. This ratio is the same for every circle, approximately equal to 3.1415926.

A right prism has a volume of 1,000 cm³ and a base area of 50 cm².
If the height is increased by 2 cm and the base area is modified such that it increases by 20%, calculate the new volume of the prism.
1320 cm³

For a rectangular prism, if the length, width, and height are all odd numbers, the surface area always be an even number. (Yes/No)
Why or why not?
Yes, the surface area of a rectangular prism must be an even number if the length, width, and height are all odd. This is because the surface area formula involves multiplying by 2, which ensures the result will be even.
