Calculating Surface Area of Rectangular Prisms

The video tutorial explains how to calculate the surface area of a rectangular prism by identifying congruent faces and calculating the area of each set of congruent rectangles. It covers the dimensions of the rectangles, the concept of congruency, and the final calculation of the total surface area, which is 62 square centimeters.

What does it mean when two shapes are congruent?

• They have the same color.

• They have the same size and shape.

• They are both rectangles.

• They have the same perimeter.

What is the area of one of the first set of congruent rectangles?

• 20 square centimeters

• 10 square centimeters

• 5 square centimeters

• 15 square centimeters

If a rectangle's dimensions are doubled, how does its area change?

• It remains the same.

• It quadruples.

• It halves.

• It doubles.

What does the term 'congruent' specifically refer to in geometry?

• Identical shapes and sizes

• Shapes with the same area

• Similar shapes with different sizes

• Shapes with the same perimeter

How many sets of congruent rectangles are identified in the tutorial?

• Five

• Four

• Three

• Two

What are the dimensions of the second set of congruent rectangles?

• 2 by 5

• 3 by 5

• 2 by 3

• 5 by 5

What is the total area of the third set of congruent rectangles?

• 15 square centimeters

• 20 square centimeters

• 12 square centimeters

• 30 square centimeters

How is the total surface area of the rectangular prism calculated?

• By adding the area of all faces

• By doubling the area of one face

• By multiplying the length by width

• By finding the volume

What is the surface area of the rectangular prism?

• 62 square centimeters

• 42 square centimeters

• 52 square centimeters

• 72 square centimeters

How many times is each dimension used in the equation for the surface area of a rectangular prism with three different lengths?

• Four times

• Three times

• Twice

• Once
