surface area of 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 total surface area of a cube with a side length of 4 inches?

Back

Surface Area = 6s² = 6(4)² = 96 square inches.

Front

Define a prism.

Back

A prism is a 3D shape with two parallel, congruent bases connected by rectangular faces.

Front

What is the surface area of a triangular prism with a base area of 20 cm² and a height of 10 cm?

Back

Surface Area = 2(base area) + perimeter of base * height = 2(20) + (perimeter of base * 10).

Front

How many faces does a triangular prism have?

Back

A triangular prism has 5 faces.

Front

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

Back

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

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 pyramid?

Back

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

Front

What is the surface area of a square prism with a base side of 6 cm and height of 10 cm?

Back

Surface Area = 2(6²) + 4(6)(10) = 72 + 240 = 312 cm².

Front

What is the surface area of a prism with a base perimeter of 30 cm and a height of 12 cm?

Back

Surface Area = 2(base area) + (perimeter of base * height).
