Doubling and Halving Volume of Rectangular Prisms

What is the primary objective of today's lesson?

• To understand the Pythagorean theorem

• To learn about the properties of shapes

• To calculate the surface area of prisms

• To double and halve the volume of rectangular prisms

If a rectangular prism has dimensions of 15ft by 4ft by 4ft, what is its volume?

• 480 cubic feet

• 60 cubic feet

• 240 cubic feet

• 120 cubic feet

To double the volume of a rectangular prism, how many dimensions need to be doubled?

• Two

• Three

• One

• None

If the volume of a rectangular prism is doubled by stacking another of the same size on top, what changes?

• Length only

• Height only

• Length and width

• Width only

To double the volume of a rectangular prism, which dimension could be doubled?

• Length

• Width

• Height

• Any of the dimensions

What is one way to halve the volume of a rectangular prism?

• Halve all dimensions

• Halve one dimension

• Double the length

• Double the height

If a rectangular prism has a volume of 160 cubic feet, what would be its volume after halving one dimension?

• 40 cubic feet

• 160 cubic feet

• 320 cubic feet

• 80 cubic feet

Does it matter which dimension is halved to achieve half the volume of a rectangular prism?

• Yes, it must be the width

• No, any dimension can be halved

• Yes, it must be the length

• Yes, it must be the height

What happens to the dimensions of a rectangular prism when its volume is halved?

• The dimensions remain the same

• Only one dimension is halved

• Only the length is halved

• All dimensions are halved

If a rectangular prism's volume is 80 cubic feet after halving, what was the original volume?

• 40 cubic feet

• 320 cubic feet

• 160 cubic feet

• 120 cubic feet
