Various surface area worksheets in finding the surface area of spheres and hemispheres, prisms such as cube, rectangular prisms, cylinders and pyramids with different bases such as square, rectangle, circle and triangle are included. One fine example for pyramid is cone.
Finding the surface area of the prisms are quite easier than other shapes. Find the perimeter of base of the prism and multiply it with height of the prism which provides lateral surface area of prism. Find the base areas separately and add them with lateral surface area.
In case of pyramids, we use a simple formula to find the total surface area.
Surface area of pyramids =1/2 * perimeter of the base * slant height of the pyramid + area of the base.
Combined surface area worksheets include word problems, simple problems, with decimals or without decimals and with or without approximation.
