Surface Area Triangular Prisms

What is the formula for the volume of a triangular prism?

• V = Base Area x Height

• V = 1/2 x Base x Height

• V = Length x Width x Height

• V = Base Area + Height

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

• SA = (Base Area x 2) + (Perimeter of Base x Height)

• SA = Base Area + Perimeter of Base + Height

• SA = (Base Area x Height) + (Perimeter of Base x 2)

• SA = (Base Area x 3) + (Perimeter of Base x Height)

How do you calculate the area of a triangle?

• Area = @@rac{1}{2} imes Base imes Height@@

• Area = Base + Height

• Area = Base imes Height

• Area = @@rac{1}{3} imes Base imes Height@@

What is the lateral surface area of a prism?

• The lateral surface area of a prism is the sum of the areas of all the lateral faces, excluding the bases.

• The lateral surface area of a prism is equal to the area of the base multiplied by the height.

• The lateral surface area of a prism is the total area of the bases only.

• The lateral surface area of a prism is the perimeter of the base multiplied by the height.

How do you find the height of a triangle if the area and base are known?

• Height = @@rac{Area}{Base}@@

• Height = @@rac{2 imes Area}{Base}@@

• Height = @@Area imes Base@@

• Height = @@rac{Base}{Area}@@

What is the significance of understanding surface area in real-life applications?

• It is crucial for determining the volume of objects.

• It helps in calculating the weight of materials.

• Understanding surface area is important for tasks such as painting, packaging, and construction, where material coverage is needed.

• It is only relevant in theoretical mathematics.

If a triangular prism has a base area of 30 cm² and a height of 10 cm, what is the total surface area?

• 300 cm²

• 240 cm²

• 180 cm²

• 120 cm²

If the base of a triangle is 10 cm and the height is 5 cm, what is the area?

• 15 cm²

• 20 cm²

• 25 cm²

• 30 cm²

What is the difference between total surface area and lateral surface area?

• Total surface area includes the areas of the bases and the lateral faces, while lateral surface area only includes the areas of the lateral faces.

• Total surface area only includes the areas of the bases, while lateral surface area includes the areas of the bases and the lateral faces.

• Total surface area is the sum of the lateral surface area and the area of one base only.

• Lateral surface area includes the areas of the bases, while total surface area only includes the lateral faces.

How do you find the perimeter of a triangle?

• Perimeter = Side1 + Side2 + Side3

• Perimeter = 2 * (Side1 + Side2)

• Perimeter = Side1 * Side2 * Side3

• Perimeter = Side1 - Side2 - Side3
