Question

what is the formula for lateral area?

Answer 1

That depends on the solid. For a cylinder, the lateral surface area is the height of the cylinder times the circumference of the base circle.

Answer 2

oops! sorry its for a rectangular prism!

Answer 3

In this case, it's just the area of each of the 4 rectangles along the sides of the prism.

if the prism is h units tall, l units long, and w units wide, the lateral surface area is 2h*(l+w)

Answer 4
