The general formula for the lateral surface area of a regular pyramid is: lateral area=2×perimeter of base×slant height of pyramid This formula essentially finds the area that makes up each lateral face by the classic formula for area of a triangle, which is: Area=base×height The per...
2 Volume of a cylinder: V =Bh or V =πr h where B is the area of the base (which is a circle and thus gives the second formula) and h is the height of the cylinder. Regular Pyramid 1 Surface area of a regular pyramid: S =B + Pl S is the surface area, B is the area ...

Step 2: Substitute the known values into the formulaWe know the lateral surface area is 352cm2 and the height h=7cm. Substituting these values into the formula:352=2×227×r×7 Step 3: Simplify the equationFirst, simplify the equation:352=2×227×r×7The 7 in the numerator and denomina...
Lateral Surface Area of a Rectangular Prism:In geometry, a prism is a three-dimensional object with two parallel, polygonal top and bottom sides called bases and lateral sides that are parallelograms. If a prism has rectangles as its bases, then the prism is called a rectangular prism....
