Understanding Surface Area of Prisms

What does surface area measure in a 3D shape?

• The distance around the shape

• The length of all the edges combined

• The combined area of all faces or surfaces

• The volume inside the shape

What unit is not used to measure surface area?

• Cubic centimeters

• Square meters

• Square kilometers

• Hectares

What is the first step in calculating the surface area of a prism?

• Measuring the height

• Calculating the volume

• Adding the area of all faces

• Drawing the net of the shape

For calculating the surface area, why is drawing the net of the shape recommended?

• It automatically calculates the area for you.

• It is the only way to calculate surface area.

• It helps in visualizing the 3D shape better.

• It reduces the size of the shape.

How many square meters is the surface area of a cube with a side of 3 meters?

• 54 square meters

• 81 square meters

• 108 square meters

• 27 square meters

What is the surface area of the front face of the rectangular prism if it is 10cm by 6cm?

• 100 square centimeters

• 60 square centimeters

• 16 square centimeters

• 600 square centimeters

How many square centimeters is the total surface area of the rectangular prism?

• 148 square centimeters

• 448 square centimeters

• 248 square centimeters

• 348 square centimeters

What is the area of one of the triangular faces of the triangular prism?

• 120 square meters

• 60 square meters

• 240 square meters

• 30 square meters

What is the total surface area of the triangular prism?

• 776 square meters

• 976 square meters

• 676 square meters

• 876 square meters

Why is it important to show your work when calculating surface area?

• It helps the teacher understand your thought process.

• It increases the surface area.

• It is not necessary if the answer is correct.

• It makes the calculation faster.
