Computing Surface Area of Rectangular Prisms

The video tutorial explains how to compute the surface area of rectangular prisms, using a real-world problem involving cereal boxes. It covers the concept of surface area, sets up a word problem, and demonstrates the calculation of surface area for different sized rectangles. Finally, it estimates how many cereal boxes can be produced with the remaining cardboard using division and rounding techniques.

What is the surface area of a 3D solid?

• The length of its edges

• The sum of the areas of its faces

• The volume of the solid

• The weight of the solid

How many different sizes of faces does a rectangular prism have?

• Two

• Three

• One

• Four

What is the first step in solving the cereal box problem?

• Calculate the volume of the box

• Determine the surface area of the box

• Measure the height of the box

• Find the weight of the box

What are the dimensions of the smallest rectangle on the cereal box?

• 4 inches by 8 inches

• 2 inches by 10 inches

• 6 inches by 10 inches

• 2 inches by 6 inches

How many more cereal boxes can be produced with the remaining cardboard?

• Three

• Four

• Five

• Six
