Exploring Adding and Subtracting Rational Expressions

What does the term 'surface area' refer to in the context of 3D figures?

• The area needed to cover the figure

• The perimeter of the figure's base

• The volume inside the figure

• The length of the figure

What is a 'net' in relation to a three-dimensional figure?

• The unfolded form of the figure

• A type of mesh used for 3D modeling

• A mathematical formula for volume

• A tool for measuring dimensions

How do you calculate the surface area of a rectangular prism using its net?

• Subtract the smallest side from the total area

• Divide the total area by the number of sides

• Add the areas of all the sides

• Multiply the length by the width and height

What formula is used to calculate the surface area of a rectangular prism?

• 2(lw + lh + wh)

• lwh

• 2lw + 2lh + 2wh

• lw + lh + wh

In the example, if the length is 8m, width 6m, and height 7m, what is the surface area using the formula?

• 292 m²

• 256 m²

• 214 m²

• 348 m²

How does the area of the front and back of the prism relate in the calculation?

• They are added separately

• Only the front is considered

• They are considered the same and multiplied by two

• They are averaged

What practical use does knowing the surface area of a box have?

• Determining the amount of paint needed

• Calculating the weight of the box

• Measuring the box's capacity

• Estimating the production costs

Why is it important to understand both the net and formula methods of finding surface area?

• To ensure accuracy in different scenarios

• Only the formula method is necessary

• The net method is outdated

• Both methods give different results

What should you do if you do not understand a part of the lesson?

• Only focus on the practical examples
