Finding the Surface Area of a Rectangular Prism

What is the formula for calculating the surface area of a rectangular prism?

• lw + lh + wh

• 2lw + 2lh + 2wh

• l + w + h

• 2(lw + lh + wh)

What is the significance of assigning names to the dimensions (length, width, height) of the prism?

• It is only for visual understanding

• It does not affect the calculations

• Both B and C

• It is crucial for correct calculations

If the length is 10 feet and the width is 4 feet, what is the area of one of the top or bottom faces?

• 40 square feet

• 14 square feet

• 50 square feet

• 20 square feet

How do you calculate the total area of the top and bottom faces together?

• Add the area of top and bottom

• Multiply the area of one face by 4

• Divide the area of one face by 2

• Multiply the area of one face by 2

What is the area of the front face if the length is 10 feet and the height is 5 feet?

• 15 square feet

• 50 square feet

• 45 square feet

• 25 square feet

How is the total area for the front and back faces calculated?

• By subtracting the area of one face from the other

• By adding the areas of both faces

• By multiplying the area of one face by 3

• By dividing the area of one face by 2

If the width is 4 feet and the height is 5 feet, what is the area of one of the left or right faces?

• 20 square feet

• 40 square feet

• 9 square feet

• 25 square feet

What does the term '2wh' represent in the context of calculating surface area?

• Sum of width and height

• Product of width, height, and 2

• Division of width by height multiplied by 2

• Twice the product of width and height

What is the total surface area of the prism if the top and bottom are 80 sq ft, front and back are 100 sq ft, and left and right are 40 sq ft?

• 180 square feet

• 200 square feet

• 240 square feet

• 220 square feet

Which method can be used to understand the surface area of a rectangular prism?

• By visualizing the calculation of each face

• Neither methods

• By memorizing the formula

• Both memorizing and visualizing
