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

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

Back

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

Front

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

Back

Total Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 cm².

Front

What shape is the base of a triangular pyramid?

Back

Triangle.

Front

What is the surface area of a square pyramid with a base of 4 ft and a height of 5 ft?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height) = 16 + (1/2 * 16 * 5) = 16 + 40 = 56 ft².

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

If a rectangular prism has a length of 10 cm, width of 5 cm, and height of 2 cm, what is its surface area?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 cm².

Front

What is the surface area of a triangular prism with a base area of 12 cm² and a height of 10 cm?

Back

Surface Area = 2 * Base Area + Perimeter of Base * Height = 2*12 + (Perimeter of Base * 10).

Front

What is 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 cylinder with a radius of 3 cm and height of 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(5 + 3) = 48π cm².
