Surface Area Introduction

What 3D solid does a triangular prism have?

• A cube with six square faces

• A triangular prism with two triangular bases and three rectangular faces

• A cylinder with circular bases

• A pyramid with a square base and four triangular faces

What is the surface area of a rectangular face of a prism?

• The surface area is calculated by adding the length and width.

• The surface area is calculated by multiplying its length by its width.

• The surface area is calculated by subtracting the width from the length.

• The surface area is calculated by dividing the length by the width.

What is a net in geometry?

• A two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

• A type of geometric figure that has no dimensions.

• A three-dimensional shape that cannot be unfolded.

• A flat surface that cannot be folded.

What is the surface area of a sphere?

• Surface Area = 2πr

• Surface Area = 4πr

• Surface Area = 4πr²

• Surface Area = πr²

What is the unit of measurement for surface area?

• square inches (in²)

• cubic inches (in³)

• linear inches (in)

• square feet (ft²)

If the surface area of a triangular prism is 170 cm², what does this represent?

• The volume of the triangular prism.

• The total area of all the surfaces of the triangular prism.

• The height of the triangular prism.

• The perimeter of the base of the triangular prism.

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

• 80 cm²

• 94 cm²

• 70 cm²

• 60 cm²

What is the formula for the area of a triangle?

• Area = base * height

• Area = 1/2 * base * height

• Area = base + height

• Area = base - height

What is the relationship between surface area and volume in 3D shapes?

• Surface area measures the total area of the surface, while volume measures the space contained within the shape.

• Surface area and volume are the same measurements for 3D shapes.

• Surface area is always greater than volume in any 3D shape.

• Volume is a measure of the surface area of a shape.

How does increasing the dimensions of a shape affect its surface area?

• It decreases the surface area.

• It has no effect on the surface area.

• Increasing the dimensions generally increases the surface area, but the relationship can vary depending on the shape.

• It only increases the surface area for certain shapes.
