Finding the Surface Area of Triangular Prisms

The video tutorial explains how to find the surface area of triangular prisms by calculating the area of their faces. It begins with an introduction to the concept of surface area and triangular prisms, followed by a detailed example problem. The tutorial provides step-by-step instructions for calculating the surface area, including substituting formulas and numeric values. It concludes with a review of the process and additional tips for accurate calculations.

What is the formula to find the area of a triangle?

• Base times height

• 1/2 times base times height

• Base plus height

• Base divided by height

How many faces does a triangular prism have?

• Two triangular and three rectangular faces

• Three triangular and three rectangular faces

• Three triangular and two rectangular faces

• Two triangular and two rectangular faces

In the example, what are the dimensions of the purple rectangle?

• 5 cm by 6 cm

• 4 cm by 6 cm

• 6 cm by 8 cm

• 5 cm by 8 cm

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

• 152 square centimeters

• 160 square centimeters

• 148 square centimeters

• 140 square centimeters

Why can the formula for the area of two triangles be simplified to base times height?

• Because the base and height are equal

• Because two triangles form a parallelogram

• Because two triangles form a rectangle

• Because the triangles are congruent
