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

• Total surface area includes all surfaces, while lateral surface area includes only the sides, excluding the top and bottom.

• Total surface area is always larger than lateral surface area.

• Lateral surface area includes all surfaces, while total surface area includes only the sides.

• Total surface area is the sum of lateral surface area and the area of the top and bottom.

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

• Surface Area = 2(lw + lh + wh)

• Surface Area = l + w + h

• Surface Area = 2(l + w + h)

• Surface Area = lw + lh + wh

What is the formula for calculating the area of a triangle?

• Area = (1/2) × base × height.

• Area = base × height

• Area = (1/3) × base × height

• Area = base + height
