Volume Calculations of Prisms

The video tutorial explains how to calculate the volume of rectangular prisms, comparing it to cubes. It provides two examples with different dimensions and demonstrates the calculation process. The tutorial then presents examination questions involving composite prisms and prisms with cutouts, explaining how to treat them as separate prisms for volume calculation. The key is to add or subtract volumes as needed to find the overall volume.

What is the formula for calculating the volume of a rectangular prism?

• Width x Height

• Length + Width + Height

• Length x Width x Height

• Length x Width

How does the volume calculation of a rectangular prism differ from that of a cube?

• The formula is different

• The dimensions can vary in a rectangular prism

• A cube has more sides

• All sides are equal in a rectangular prism

In the first example, what is the volume of the rectangular prism with dimensions 50mm x 40mm x 100mm?

• 150,000 mm³

• 200,000 mm³

• 240,000 mm³

• 100,000 mm³

What is the volume of a rectangular prism with a height of 100mm, width of 40mm, and length of 50mm?

• 150 cm³

• 240 cm³

• 200 cm³

• 100 cm³

In the second example, what is the volume of the rectangular prism with dimensions 40mm x 50mm x 120mm?

• 100,000 mm³

• 240,000 mm³

• 150,000 mm³

• 200,000 mm³

What is the volume of a rectangular prism with a height of 120mm, width of 50mm, and length of 40mm?

• 200 cm³

• 240 cm³

• 150 cm³

• 100 cm³

How can a complex object be simplified for volume calculation?

• By ignoring the smaller parts

• By treating it as a single prism

• By using a different formula

• By dividing it into separate prisms

When calculating the volume of a complex object, what should you do after finding the volumes of separate prisms?

• Multiply the volumes

• Divide the volumes

• Add the volumes together

• Subtract the smaller volume from the larger

In the complex object example, what is the volume of prism A if its dimensions are 100mm x 110mm x 120mm?

• 1,000,000 mm³

• 1,100,000 mm³

• 1,320,000 mm³

• 1,200,000 mm³

In the complex object example, what is the volume of prism B if its dimensions are 50mm x 55mm x 60mm?

• 140,000 mm³

• 145,000 mm³

• 150,000 mm³

• 165,000 mm³
