Surface Area of Prisms Concepts

The video tutorial explains how to calculate the surface area of prisms using two different approaches. It begins with a rectangular prism, detailing the process of calculating the area of each face and summing them up. The tutorial then moves on to a hexagonal prism, demonstrating how to dissect the shape and calculate the area of its bases and lateral sides. The video concludes with a summary of the formulas used, emphasizing the importance of understanding the perimeter, height, and base area in these calculations.

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

• Multiply the height by the width

• Find the perimeter of the base

• Consider each face as a separate rectangle

• Calculate the volume of the prism

How do you find the area of the top and bottom faces of a rectangular prism?

• Add the lengths of all edges

• Multiply the area of one face by two

• Divide the perimeter by two

• Subtract the area of the sides from the total area

What is the next step after calculating the area of the top and bottom faces of a rectangular prism?

• Subtract the base area from the total area

• Measure the diagonal of the prism

• Find the volume of the prism

• Calculate the area of the front and back faces

What is the formula used to find the area of a hexagon?

• Length times width

• Base times height

• Perimeter squared

• One half times the apothem times the perimeter

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

• Divide the perimeter by the height

• Subtract the base area from the total area

• Add the areas of the bases

• Multiply the perimeter by the height

What is the final step in finding the surface area of a hexagonal prism?

• Add the lateral area and the base areas

• Divide the total area by two

• Subtract the lateral area from the base area

• Multiply the base area by the height

What does 'P' stand for in the formula for the surface area of a prism?

• Prism

• Polygon

• Perimeter

• Parallel

In the context of prisms, what does 'BA' represent?

• Base Area

• Base Angle

• Boundary Area

• Basic Angle

What is the significance of the height in calculating the surface area of a prism?

• It is used to calculate the volume

• It is subtracted from the perimeter

• It is added to the base area

• It is multiplied by the perimeter to find the lateral area

What is the total surface area of a hexagonal prism with a lateral area of 480 square units and base areas totaling 288 square units?

• 816 square units

• 480 square units

• 768 square units

• 288 square units
