Calculating Surface Area of Triangle Prisms for Grade 7

A triangular prism has a base with a height of 5 cm and a base length of 6 cm. If the prism is 10 cm long, what is its surface area?

• 15 + 30 + 25 + (√80 * 10) cm²

• 30 + 60 + 50 + (√61 * 10) cm²

• 20 + 40 + 30 + (√50 * 10) cm²

• 25 + 50 + 45 + (√70 * 10) cm²

A triangular prism has a triangular base with sides measuring 3 cm, 4 cm, and 5 cm. If the height of the prism is 12 cm, calculate the surface area of the prism.

• 156 cm²

• 180 cm²

• 144 cm²

• 120 cm²

A triangular prism has a base area of 24 cm² and a height of 8 cm. What is the total surface area of the prism if the lateral faces are rectangles?

• Total surface area = 2 * Base area + 8 = 56 cm²

• Total surface area = Lateral surface area + 2 * Base area = P * 8 + 2 * 24 = P * 8 + 48 cm² (where P is the perimeter of the triangular base)

• Total surface area = 3 * Base area + Lateral surface area = 72 cm²

• Total surface area = P * 10 + 48 cm²

The base of a triangular prism is an equilateral triangle with a side length of 10 cm. If the height of the prism is 15 cm, find the surface area of the prism.

• 300 + 20sqrt(3) cm²

• 500 cm²

• 400 cm²

• 450 + 50sqrt(3) cm²

A triangular prism has a base with a height of 7 cm and a base length of 8 cm. If the prism is 5 cm long, what is the surface area?

• 184.15 cm²

• 175 cm²

• 150 cm²

• 200 cm²

A triangular prism has a base that is a right triangle with legs measuring 6 cm and 8 cm. If the height of the prism is 10 cm, calculate the surface area of the prism.

• 320 cm²

• 240 cm²

• 288 cm²

A triangular prism has a base with a height of 4 cm and a base length of 9 cm. If the prism is 6 cm long, what is its surface area?

• 150 cm²

• 100 cm²

• 120 cm²

• 138 cm²

A triangular prism has a triangular base with a base of 5 cm and a height of 12 cm. If the height of the prism is 10 cm, what is the total surface area?

• 352.5 cm²

• 300 cm²

• 250 cm²

• 400 cm²

A triangular prism has a base area of 30 cm² and a height of 10 cm. What is the total surface area of the prism if the lateral faces are rectangles?

• Total Surface Area = 30 cm² + (P * 5 cm)

• Total Surface Area = 100 cm² + (P * 10 cm)

• Total Surface Area = 60 cm² + (P * 10 cm) where P is the perimeter of the triangular base.

• Total Surface Area = 60 cm² + (P * 15 cm)

A triangular prism has a base that is an isosceles triangle with a base of 10 cm and equal sides of 13 cm. If the height of the prism is 14 cm, find the surface area of the prism.

• 450 cm²

• 500 cm²

• 620 cm²

• 582 cm²
