Surface Area of Prisms

Front

What is the formula for calculating 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 prism?

Back

The total surface area is the sum of the areas of all the faces of the prism.

Front

How many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

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

If the length of a prism is doubled, how does that affect the surface area?

Back

The surface area increases, but the exact change depends on the dimensions of the other sides.

Front

What units are used to measure surface area?

Back

Surface area is measured in square units, such as cm² or in².

Front

Calculate the surface area of a cube with a side length of 4 cm.

Back

Surface Area = 6s² = 6(4 cm)² = 96 cm².

Front

What is a prism?

Back

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

Front

How do you find the surface area of a triangular prism?

Back

Surface Area = base area + lateral area, where lateral area = perimeter of base × height.

Front

What is the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r = radius and h = height.
