Exploring Volume and Surface Area of Triangular Prisms

The video tutorial covers the calculation of the area of triangles and rectangles, including the use of circumference for rectangles. It explains the volume and surface area calculations for triangular prisms, emphasizing the concept of stacking triangles. The tutorial also includes complex volume calculations and provides practice problems to reinforce the concepts taught.

• 24 square units

How do you calculate the volume of a stack of triangular slices?

• Length of the stack times width of the base

• Sum of the areas of all triangles

• Base of the rectangle times height

• Area of the base triangle times the height of the stack
