What is the total surface area of this prism?

• 360in²

• 408n²

• 36in²

• 400.8in²

Is surface area.......

• Filling in a 3 dimensional shape

• Wrapping the outside of a 3 dimensional shape

What is surface area?

• The measure of the amount of space inside of a solid figure

• The sum of all the areas of all the shapes that cover the object

What is the lateral surface area of this retangular prism?

• 800 cm ²

• 800 cm ²

• 35 cm ²

• 600 cm ²

What is the surface area formula for a cylinder?

• A = πrl + πr²
• A = 2πrh + 2πr²
• A = 4πr²
• A = πr²

What is the surface area of the cylinder to the nearest square inch? Use 3.14.

• 625 in²

• 1300 in²

• 1046 in²

• 848 in²

What is the difference between lateral area and total surface area?

• Total surface area includes 1 base instead of 2 bases like lateral does

• Lateral includes all the faces while total only includes the bases

• Total surface area includes the base(s) and all the faces while lateral does not include the base(s)

• Lateral just includes B, the area of the base while total does not
