Review: Surface Area of Rectangular and Triangular Prisms

Front

How many Faces does a Triangular Prism have?

Back

A triangular prism has 5 faces.

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 + lP, where b = base, h = height of the triangle, l = length of the prism, P = perimeter of the base triangle.

Front

Find the total surface area of a prism with a base area of 20 cm² and a height of 4 cm.

Back

Total Surface Area = 2 * Base Area + Perimeter of Base * Height = 2(20) + P(4).

Front

What is the surface area of a rectangular prism with dimensions 3 cm, 4 cm, and 5 cm?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 94 cm².

Front

If a triangular prism has a base of 6 cm and a height of 8 cm, what is the area of the base?

Back

Area of the base = 1/2 * base * height = 1/2 * 6 * 8 = 24 cm².

Front

What is the surface area of a triangular prism with a base area of 30 cm² and a height of 10 cm?

Back

Total Surface Area = 2 * Base Area + Perimeter of Base * Height = 2(30) + P(10).

Front

How do you calculate the perimeter of a triangle with sides 3 cm, 4 cm, and 5 cm?

Back

Perimeter = 3 + 4 + 5 = 12 cm.

Front

What is the surface area of a prism with a base area of 50 cm² and a height of 6 cm?

Back

Total Surface Area = 2 * Base Area + Perimeter of Base * Height = 2(50) + P(6).

Front

What is the surface area of a rectangular prism with dimensions 2 cm, 3 cm, and 4 cm?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 52 cm².
