Surface Area of Rectangular and Triangular prisms

Front

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

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

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

Back

Surface Area = bh + l1h + l2h + l3h, where b = base, h = height of the triangle, l1, l2, l3 = lengths of the triangular sides.

Front

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

Back

Lateral Surface Area = Perimeter of the base × Height of the prism.

Front

What is the surface area of a rectangular prism with length 5 cm, width 9 cm, and height 20 cm?

Back

650 cm².

Front

What is the surface area of a triangular prism with a base area of 50 cm² and a height of 10 cm?

Back

Surface Area = 50 cm² + (Perimeter of the base × 10 cm).

Front

If a triangular prism has a base perimeter of 30 cm and a height of 12 cm, what is the lateral surface area?

Back

Lateral Surface Area = 30 cm × 12 cm = 360 cm².

Front

What is the surface area of a prism with a base area of 40 in² and a height of 5 in?

Back

Surface Area = 40 in² + (Perimeter of the base × 5 in).

Front

What is the surface area of a triangular prism with a base of 6 cm, height of 8 cm, and slant height of 10 cm?

Back

Surface Area = (1/2 × base × height) + (Perimeter × slant height).

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

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

Back

Total surface area includes all surfaces, while lateral surface area includes only the sides, excluding the top and bottom.
