Understanding Surface Area of Rectangular Prisms

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

• length + width + height

• length * width * height

• 2 * length * width + 2 * length * height + 2 * width * height

• 2 * (length + width + height)

Which dimension is typically assigned to the horizontal line of a rectangular prism?

• Diagonal

• Width

• Height

• Length

How do you calculate the area of the top face of a rectangular prism?

• Multiply the length by the width

• Multiply the length by the height

What is the combined area of the top and bottom faces of the prism if each has an area of 40t squared?

• 40t squared

• 80t squared

• 100t squared

• 120t squared

What operation is used to find the area of the front face of a rectangular prism?

• Divide the length by the height

• Subtract the height from the length
