Surface Area of Rectangular Prism

How do you calculate the surface area of a rectangular prism?

• Surface Area = 2(lw + lh + wh)

• Surface Area = l + w + h

• Surface Area = 2(l + w + h)

• Surface Area = l * w * h

What does it mean to wrap the outside of a 3D shape?

• Calculating the volume of the shape.

• Calculating the surface area, which is the total area covering the shape.

• Finding the perimeter of the base of the shape.

• Determining the shape's dimensions.

If a rectangular prism has a length of 5 cm, width of 3 cm, and height of 4 cm, what is its surface area?

• 80 cm²

• 94 cm²

• 70 cm²

• 60 cm²

What is the relationship between volume and surface area in a rectangular prism?

• Volume measures the space inside, while surface area measures the area covering the outside.

• Volume and surface area are the same measurement.

• Surface area measures the space inside, while volume measures the area covering the outside.

• Volume is always greater than surface area.

If the surface area of a rectangular prism is 200 cm², what could be its dimensions?

• 5 cm x 5 cm x 4 cm

• 10 cm x 10 cm x 2 cm

• 8 cm x 5 cm x 5 cm

• 4 cm x 4 cm x 12.5 cm

What is a net of a rectangular prism?

• A three-dimensional shape made of solid material.

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

• A type of graph used to represent data visually.

• A method of calculating the volume of a prism.

What is the surface area of a rectangular prism with a length of 10 cm, width of 5 cm, and height of 2 cm?

• 120 cm²

• 140 cm²

• 100 cm²

• 160 cm²

What is the surface area of a rectangular prism with dimensions 1 ft, 2 ft, and 3 ft?

• 20 ft²

• 22 ft²

• 24 ft²

• 18 ft²

What is a rectangular prism?

• A two-dimensional shape with four sides.

• A three-dimensional shape with six rectangular faces.
