If a rectangular prism has a length of 10 cm, width of 5 cm, and height of 4 cm, what is its lateral surface area?

Back

Lateral Surface Area = 2h(l + w) = 2(4)(10 + 5) = 120 cm².

What is the lateral surface area of a cylinder with a radius of 3 inches and a height of 5 inches?

Back

Lateral Surface Area = 2πrh = 2π(3)(5) ≈ 94.25 square inches.

Front

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

Back

Lateral surface area excludes the area of the bases, while total surface area includes both the lateral area and the area of the bases.
