Exploring Surface Area and Volume of Triangular Prisms

This video tutorial explains the difference between surface area and volume, focusing on a triangular prism. It provides a step-by-step guide to calculating the volume by finding the area of the cross-section and multiplying it by the length. The tutorial also covers the more complex process of calculating the surface area by identifying and summing the areas of all surfaces. The video concludes with a reminder to distinguish between these concepts in exams.

What is often confused in exams regarding triangular prisms?

• The height of the prism

• The weight of the prism

• The difference between surface area and volume

• The color of the prism

What is the formula to calculate the volume of a triangular prism?

• Volume = base area + height

• Volume = cross section area x length

• Volume = base area x width

• Volume = height x width x length

How do you calculate the area of the triangular cross section?

• 1/2 x Base x Height

• Base x Height

• 2 x Base x Height

• Base + Height

What is the volume of a triangular prism with a cross section area of 6 cm² and length of 7 cm?

• 42 cm³

• 13 cm³

• 48 cm³

• 21 cm³

What mistake is often made when calculating the area of the triangular cross section?

• Multiplying by 2 instead of 1/2

• Subtracting the base from the height

• Forgetting to multiply by 1/2

• Adding the base and height

How many surfaces does a triangular prism have?

• 3

• 4

• 5

• 6

What is the area of the rectangular surface at the front of the prism if it measures 5 cm by 7 cm?

• 12 cm²

• 35 cm²

• 25 cm²

• 14 cm²

What is the total surface area of the triangular prism?

• 84 cm²

• 42 cm²

• 72 cm²

• 96 cm²

What is the first step in calculating the surface area of a triangular prism?

• Measuring the prism

• Calculating the area of the triangular base

• Adding the areas of all surfaces

• Calculating the volume

Why is it important to understand the difference between surface area and volume?

• It is not important

• Both for exams and practical applications

• For practical applications in real life

• To pass exams
