Question

Find the lateral lateral surface area of cube whose edge is 11 cm the lateral surface area of cube is 100 m square find the value of the cube the radius and height of the cylinder are 10.5 cm and 16 cm respectively find its curved surface area of it

Answer 1

lateral surface area of a cube = side x side = 11 x 11 = 121 cm square

Side of cube with lateral surface area 100 m square =  square root of 100 = 10 m

Surface area of cylinder = 2 x pi x r x height = 2X 3.14 x 10.5 x 16 = 1055.04 cm square
