DIY Maths: Surface area of cubes, cuboids and triangular prisms
Read about how to calculate the surface area of cuboids and cubes, watch an animation, then try to figure out the surface area of the prism. You can also practice finding the surface area of objects with different side lengths - the interactive program will let you know how you're doing!
The surface area formulae for all prisms and cylinders are the same. They are all (two x the area of the base) plus (the perimeter of the base x the height of the object).
