Volume Calculations for Prisms

This video tutorial covers solving volume problems for various prisms, including triangular, trapezoidal, and composite figures. It provides step-by-step guidance on calculating the volume by finding the base area and multiplying it by the height. The tutorial also includes examples of calculating the volume of a barn structure and offers a summary of the methods used.

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

• Base area times height

• Length times width times height

• Base area divided by height

• Base area plus height

How do you calculate the base area of a triangle?

• Base divided by height

• Base times height

• Base plus height

• 1/2 base times height

What is the first step in finding the volume of a trapezoidal prism?

• Calculate the height of the prism

• Find the base area of the trapezoid

• Multiply the base area by the height

• Add the lengths of the bases

Which of the following is used to find the area of a trapezoid?

• Base1 times Base2

• Base times height

• Base1 plus Base2

• 1/2 (Base1 + Base2) times height

What defines a composite figure in volume calculations?

• A figure with no regular shapes

• A figure made up of two or more regular figures

• A figure with only triangular prisms

• A single regular shape

How do you find the total volume of a composite figure?

• Divide the total volume by the number of prisms

• Subtract the smallest volume from the largest

• Add the volumes of all prisms

• Multiply the volumes of all prisms

What is the volume of a rectangular prism with dimensions 40 x 50 x 15?

• 50,000 cubic feet

• 20,000 cubic feet

• 40,000 cubic feet

• 30,000 cubic feet

In the barn-shaped composite figure, what is the volume of the triangular prism part?

• 20,000 cubic feet

• 5,000 cubic feet

• 10,000 cubic feet

• 15,000 cubic feet

What is the final step in calculating the volume of a composite solid?

• Subtract the smallest volume from the largest

• Multiply all volumes together

• Add the volumes of all individual prisms

• Divide the total volume by the number of prisms

How do you find the volume of a composite solid formed by two or more prisms?

• Find the volume of each prism and add them together

• Find the volume of the largest prism only

• Subtract the volume of the smallest prism from the largest

• Multiply the volumes of all prisms
