Surface area and volume
Which surface area and volume equations would you say is necessary to learn for maths. Particularly surface area
Reply 1
Sphere: V=(4/3)pi*(r^3)
Cylinder: V=pi*(r^2)*h
Cone: V=(1/3)pi*(r^2)*h
Cuboid: V=lbh
Pyramid: V=(1/3)A*h
Circle: A=pi*(r^2)
Rectangle: A=lb
With surface area it’s pretty easy just sum up all the areas of the shapes composing the shape.
