Frequently asked questions
What formula does this calculator use?
Volume = b^2 × h ÷ 3; Slant height = sqrt((b ÷ 2)^2+h^2); Surface area = b^2+2 × b × sl. Variables: b = base side, h = height.
What do I need to enter?
You need base side, height. Results update as you type.
What is an example result?
