Volume of Prisms: Understanding Cross-sectional Areas and Depth

What characteristic do all prisms share?

• They have the same cross-sectional area throughout.

• They have a circular base.

• They have no edges.

• They are always rectangular.

How do you find the volume of a prism?

• Multiply the base area by the height.

• Divide the cross-sectional area by the depth.

• Add the base area to the height.

• Multiply the cross-sectional area by the depth.

Which formula is used to calculate the area of a circle?

• π times the radius squared

• Half the base times the height

• Base times height

• Length times width

What is the formula for the area of a triangle?

• Base times height

• Length times width

• Half the base times the height

• π times the radius squared

If given the volume and depth of a prism, how can you find the cross-sectional area?

• Divide the volume by the depth.

• Add the volume to the depth.

• Multiply the volume by the depth.

• Subtract the depth from the volume.

What is the first step in finding the volume of a complex shape?

• Measure the depth.

• Find the cross-sectional area of the face.

• Estimate the volume.

• Calculate the perimeter.

Why is it important to know geometric formulas when calculating volumes?

• To estimate the weight of the shape.

• To accurately find the area of the cross-section.

• To determine the color of the shape.

• To find the perimeter of the shape.
