Question

Find the ratio of volume of a cube having side 12 units to surface area of the cube.​

Answer 1

volume of cube is length ×length ×length

=12×12×12= 1728

surface area= 6×length ×length =

6×12×12=864

ratio=1728÷864= 2

Find the ratio of volume of a cube having side 12 units to surface area of the cube.​

                                                       

║⊕ANSWER⊕║

GIVEN

Side of the cube = 12 units

Volume of a cube = a³

Surface area of a cube = 6a²

Volume of cube = (12)³

                            = 1728 cube units

Surface area of the cube = 6(12)²

                                           = 864 square units

Required ratio = 1728/864

                         = 1:2
