Finding Missing Dimensions Using the Volume Formula

This lesson teaches how to find missing dimensions using the volume formula. It begins with a review of prisms and volume measurement, followed by an example of calculating the volume of a rectangular prism. The lesson then demonstrates solving for missing dimensions and includes a challenging problem involving unit conversion. The lesson concludes with a summary of the key points.

What is the primary characteristic of a prism?

• It has circular faces.

• It is a two-dimensional object.

• It has six rectangular faces.

• It is always a cube.

How do you calculate the volume of a rectangular prism?

• Add the length, width, and height.

• Multiply the length, width, and height.

• Subtract the width from the length.

• Divide the height by the width.

In the example given, what is the volume of the prism with dimensions 10mm x 1mm x 2mm?

• 20 cubic millimeters

• 40 cubic millimeters

• 10 cubic millimeters

• 30 cubic millimeters

What is the first step in solving a problem with different units of measurement?

• Add all the measurements together.

• Convert all measurements to the same unit.

• Use only the largest measurement.

• Ignore the units and solve directly.

If an aquarium has a base of 2 feet by 10 inches, what is the height if the volume is known?

• 14 inches

• 12 inches

• 16 inches

• 10 inches
