Calculating Volumes of Prisms and Cylinders

What defines a prism in geometry?

• A three-dimensional object with no identical bases

• A shape with two identical bases and all sides are rectangles

• A two-dimensional shape extended in the third dimension

• A shape with only one base that is a circle

What is the volume of a shape measured in?

• Linear units

• Circular units

• Cubic units

• Square units

What is the formula to calculate the volume of prisms and cylinders?

• Volume = base area + height

• Volume = base area / height

• Volume = base area * height

• Volume = (base area)^2 * height

How do you find the area of a triangle's base?

• Base + Height

• (Base * Height) / 2

• Base * Height

• (Base + Height) / 2

What is the shape of the base for a rectangular prism?

• Rectangle

• Triangle

• Trapezoid

• Circle

How do you calculate the area of a rectangle?

• Length * Width

• (Length + Width) / 2

• Length + Width

• Length / Width

What is the correct formula to find the area of a trapezoid?

• (Height + Base1 + Base2) / 3

• 1/2 * Height * (Base1 + Base2)

• Height * (Base1 + Base2)

• 1/2 * (Base1 * Base2)

What distinguishes a cylinder from a prism?

• It is a two-dimensional shape

• It has two identical circular bases and a curved side

• It has a rectangular base

• It has no identical bases

How do you find the area of a circle?

• 2 * Pi * Radius

• Pi * Radius^2

• Pi * Radius

• Pi * Diameter

Why do we use the term 'approximately equal to' when calculating the area of a circle?

• Because we use an exact value of Pi

• Because the diameter can vary

• Because we estimate the value of Pi

• Because the radius is always an approximation
