Exploring Surface Area of Prisms

What is the definition of surface area?

• The length of the figure

• The volume of the figure

• The sum of all the faces of a three-dimensional figure

• The perimeter of the base of a figure

What is a 'net' in the context of three-dimensional figures?

• A type of graph

• A tool for catching fish

• A flat representation of all faces of the figure

• A mathematical formula

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

• Add the area of the base to the height

• Multiply the length by the width and height

• Add the areas of all the faces together

• Divide the volume by the height

What is the surface area of a rectangular prism with a base of 4x4 inches and height of 9 inches?

• 148 square inches

• 176 square inches

• 184 square inches

• 164 square inches

In the practice problem, what is the surface area of the rectangular prism?

• 132 square centimeters

• 142 square centimeters

• 138 square centimeters

• 126 square centimeters

Can surface area calculations be applied to shapes other than rectangular prisms?

• No, only to rectangular prisms

• No, it's limited to cubes

• Yes, to any three-dimensional figure

• Yes, but only to circular shapes

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

• Subtract the base area from the total volume

• Divide the volume by the height of the prism

• Add the area of the base triangles and the lateral faces

• Multiply the base area by the height

What is the surface area of the triangular prism example given in the video?

• 166 square feet

• 146 square feet

• 156 square feet

• 136 square feet

In the final practice problem, what is the correct calculation for the surface area of the triangular prism?

• The sum of the areas of all faces

• The product of the base area and height

• The volume divided by the height

• The difference between the lateral area and the base area

What is the importance of being organized when calculating surface area?

• It is not important at all

• It reduces the calculation time by half

• It makes the figure look nicer

• It helps in accurately adding all areas together
