Finding Missing Dimensions in Prisms

This video tutorial teaches how to find missing dimensions of a prism using the volume formula. It begins with a review of prisms and volume, followed by examples of calculating volume and solving for missing dimensions. The tutorial includes a challenging problem involving unit conversion to find the height of an aquarium.

What is the primary focus of this lesson?

• Finding missing dimensions using the volume formula

• Finding missing dimensions using the area formula

• Understanding the properties of circles

• Calculating surface area of prisms

Which of the following is true about a prism?

• It has four triangular 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?

• Divide the height by the width

• Add the length, width, and height

• Multiply the length, width, and height

• Subtract the width from the length

If a prism has a length of 10 units, a width of 3 units, and a height of 4 units, what is its volume?

• 60 cubic units

• 120 cubic units

• 30 cubic units

• 40 cubic units

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

• 10 cubic millimeters

• 30 cubic millimeters

• 40 cubic millimeters

• 20 cubic millimeters

What is the width of the box if the volume is given and other dimensions are known?

• 4 inches

• 5 inches

• 3 inches

• 2 inches

When solving for a missing dimension, what must be true about the units?

• They can be in any units

• They must all be in the same units

• They must all be in feet

• They must all be in meters

In the challenging problem, what is the height of the aquarium after converting units?

• 10 inches

• 12 inches

• 14 inches

• 16 inches

What is the first step in solving for a missing dimension when given different units?

• Ignore the units

• Add all the measurements together

• Multiply all measurements by two

• Convert all measurements to the same unit

What is the final step in finding a missing dimension using the volume formula?

• Divide the volume by the known dimensions

• Add the volume to the known dimensions

• Multiply the volume by the known dimensions

• Subtract the volume from the known dimensions
