Surface Area of Prisms and Pyramids

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 area and height = height of the prism.

Front

What is the formula for the surface area of a pyramid?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

How do you calculate the surface area of a triangular pyramid?

Back

Surface Area = (1/2 * base * height) + (1/2 * perimeter of base * slant height).

Front

What is the surface area of a triangular prism with a base area of 30 cm², height of 10 cm, and perimeter of base 24 cm?

Back

Surface Area = 30 + (24 * 10) = 270 cm².

Front

What is the surface area of a square pyramid with a base length of 6 cm and slant height of 8 cm?

Back

Surface Area = 6² + (1/2 * 4 * 8) = 36 + 16 = 52 cm².

Front

What is the surface area of a cylinder?

Back

Surface Area = 2πr² + 2πrh, where r = radius and h = height.

Front

What is the surface area of a cone?

Back

Surface Area = πr² + πrl, where r = radius and l = slant height.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.

Front

How do you find the surface area of a composite shape?

Back

Calculate the surface area of each individual shape and then sum them up.
