Surface Area and Volume of Prisms

The video tutorial reviews how to find the surface area of prisms, focusing on triangular and rectangular prisms. It explains the importance of identifying the bases of prisms and provides step-by-step calculations for determining the surface area. The tutorial includes examples for both triangular and rectangular prisms, highlighting the formulas used and the process of calculating perimeter, base area, and height. The video also distinguishes between total and lateral surface area.

What is the base shape of a triangular prism?

• Rectangle

• Circle

• Triangle

• Square

How do you calculate the perimeter of the base of a triangular prism?

• Add all the sides of the base

• Subtract the height from the base

• Multiply the length by the width

• Divide the base by the height

What formula is used to find the area of a triangular base?

• Base times height

• Perimeter times height

• Base times height divided by 2

• Length times width

What additional information is needed to calculate the surface area of a prism besides the perimeter and area of the base?

• Diagonal of the prism

• Width of the base

• Height of the prism

• Volume of the prism

What is the lateral surface area of a prism?

• The area excluding the bases

• The volume of the prism
