Calculating Surface Area and Volume of Prisms

What does surface area measure in a 3D object?

• The amount of space inside the object

• The weight of the object

• The amount of material needed to cover the object

• The length of the object's edges

What does the surface area of a 3D object represent?

• The length of the object's base

• The volume of the object

• The total area of all its faces

• The height of the object

What is a key characteristic of a prism?

• It has the same shape on all sides

• It changes shape when cut

• It retains the same cross-section throughout its length

• It has a circular base

How do you calculate the surface area of a triangular prism?

• Add the volume to the base area

• Add the area of the bases to the perimeter of the base times the height of the lateral face

• Multiply the base area by the height

• Multiply the perimeter of the base by the height of the prism

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

• Base x Height / 2

• Length x Width

• Perimeter x Height

• Length + Width + Height

How is the perimeter of a triangular base calculated?

• Multiplying the length of one side by three

• Dividing the area by the height

• Multiplying the base by the height

• Adding the length of all three sides

What is the formula for the surface area of a rectangular prism?

• 2 x (Length + Width) + (Perimeter of base x Height of lateral face)

• Length x Width x Height

• 2 x (Area of the base) + (Perimeter of base x Height of lateral face)

• Area of the base + Volume

How do you calculate the volume of a prism?

• Length x Width x Height

• Perimeter of the base x Height of the prism

• 2 x (Area of the base) + (Perimeter of base x Height)

• Area of the base x Height of the prism

What unit is used to denote volume?

• Kilograms

• Linear units

• Cubic units

• Square units

What is the volume of a rectangular prism with a base area of 15 cm squared and height of 6 cm?

• 21 cm cubed

• 90 cm cubed

• 30 cm squared

• 60 cm squared
