Exploring Surface Area of Right Prisms

The video tutorial covers the concept of right prisms, explaining their definition and key vocabulary. It details the formula for calculating the surface area of right prisms, using examples with trapezoidal and triangular bases to demonstrate the process. The tutorial emphasizes understanding the geometry and calculations involved in determining surface areas.

What defines a right prism compared to an oblique prism?

• The bases are not congruent

• The bases are not parallel

• The sides are not perpendicular to the bases

• The sides are perpendicular to the bases

What does 'congruent' mean in the context of right prisms?

• Different shapes but same size

• Different sizes but same shape

• Same size and shape

• None of the above

What does the variable 'B' represent in the formulas for right prisms?

• Perimeter of the base

• Area of the bases

• Height of the prism

• Volume of the prism

What is the formula to find the surface area of a right prism?

• Perimeter of the base times the height

• 2 times the area of the base plus the height

• Area of the base plus the perimeter of the base times the height

• 2 times the area of the base plus the perimeter of the base times the height

What does the perimeter of the base contribute to in calculating the surface area of a right prism?

• It is squared to find the area

• It is added to the area of the bases

• It is multiplied by the height to find the area of lateral faces

• It is used to find the volume

In the context of right prisms, what are lateral faces?

• The faces around the sides of the prism

• The top and bottom faces

• The faces perpendicular to the bases

• The congruent parallel faces

How is the height of a right prism defined?

• The slant height of the prism

• The distance around the base

• The perpendicular distance between the bases

• The longest side of the base

How do you calculate the area of a trapezoidal base in a right prism?

• Base times height

• Sum of all sides

• Half the sum of the bases times the height

• Length times width

What shape is the base of the right prism in the second example?

• Circle

• Triangle

• Trapezoid

• Rectangle

What is the total surface area of the triangular base right prism described in the last example?

• 352 cm²

• 430 cm²

• 624 cm²

• 192 cm²
