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 + (perimeter of base * height), where b = base, h = height of the prism.

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 × base × height.

Front

If a rectangular prism has dimensions 3 ft, 4 ft, and 6 ft, what is its surface area?

Back

108 ft².

Front

If a triangular prism has a base area of 50 cm² and a height of 10 cm, what is the surface area if the perimeter of the base is 30 cm?

Back

Surface Area = 50 + (30 * 10) = 350 cm².

Front

What is the surface area of a box that is 16 inches long, 10 inches wide, and 5 inches high?

Back

580 in².

Front

What is the significance of rounding in surface area calculations?

Back

Rounding is important for providing a practical answer, especially in real-world applications.

Front

What units are used for surface area measurements?

Back

Square units (e.g., m², in², ft², yd²).

Front

What is the surface area of a triangular prism with a base area of 100 yd² and a height of 9 yd?

Back

Surface Area = 100 + (perimeter of base * 9).
