Exploring Surface Area of Rectangular Prisms

What is the purpose of drawing a net for a rectangular prism in this lesson?

• To help visualize the faces for surface area calculation

• To improve drawing skills

• To calculate the volume of the prism

• To create a physical model of the prism

How many faces does a rectangular prism have?

• Six

• Four

• Ten

• Eight

What does the 'SA' stand for in the context of this lesson?

• Square Alignment

• Solid Angle

• Surface Area

• Segmented Area

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

• SA = 2(l + w + h)

• SA = lw + lh + wh

• SA = lwh

• SA = 2(lw + lh + wh)

What does congruent faces mean in the context of a rectangular prism?

• All faces are parallel

• All faces are the same shape

• Each face is a different size

• Opposite faces are identical in area

What real-world application was mentioned for understanding surface area?

• Finding how much cardboard is needed for a box

• Determining the amount of paint needed

• Measuring the length of the edges

• Calculating the amount of wrapping paper

In the example provided, if the length is 8 cm, width is 4 cm, and height is 6 cm, what is the surface area?

• 152 cm²

• 64 cm²

• 96 cm²

• 208 cm²

In the word problem about the geode, what are the dimensions of the box?

• Length 16 inches, width 7 inches, height 3 inches

• Length 7 inches, width 3 inches, height 16 inches

• Length 3 inches, width 16 inches, height 7 inches

• Length 5 inches, width 3 inches, height 10 inches

Why is it important to repeat writing the surface area formula?

• To avoid using a calculator

• To memorize it effectively

• To use different formulas

• To make the writing clearer

What should you do if you make a mistake in calculating surface area?

• Start over with new dimensions

• Change the formula

• Check and correct the specific error

• Ignore the mistake
