Understanding Surface Area of a Triangular Prism

This video tutorial explains how to calculate the surface area of a triangular prism. It begins by identifying the base of the prism and then describes the process of calculating the lateral area using the perimeter of the base and the height of the prism. The tutorial continues by explaining how to find the area of the triangular bases and concludes by adding the lateral and base areas to determine the total surface area. The video emphasizes understanding the geometry of the prism and applying the correct formulas to find the surface area.

What type of prism is identified by having triangular parallel sides?

• Hexagonal prism

• Cylindrical prism

• Rectangular prism

• Triangular prism

Which part of the prism is referred to as the lateral area?

• The parallel sides

• The non-parallel rectangular sides

• The entire surface

• The triangular bases

How do you calculate the lateral area of a triangular prism?

• Perimeter of base times height

• Base area plus perimeter

• Sum of all sides

• Base area times height

What is the height of the prism when flipped up?

• 16 cm

• 20 cm

• 12 cm

• 10 cm

What is the perimeter of the triangular base in the example?

• 48 cm

• 36 cm

• 28 cm

• 60 cm

What is the formula for the area of a triangular base?

• Base plus height

• Base times height

• 1/2 times base times height

• Perimeter times height

If one triangular base area is 96 cm², what is the total area for both bases?

• 384 cm²

• 96 cm²

• 192 cm²

• 48 cm²

Why is the hypotenuse not used in the area calculation of the triangular base?

• It is not needed for area calculation

• It is not parallel

• It is not part of the base

• It is too long

What is the final step to find the total surface area of the prism?

• Divide lateral area by base area

• Subtract base area from lateral area

• Add lateral area and double the base area

• Multiply lateral area by base area

What is the total surface area of the prism in the example?

• 480 cm²

• 672 cm²

• 960 cm²

• 192 cm²
