# Find the Ratio of the Total Surface Area and Lateral Surface Area of a Cube. - Mathematics

Find the ratio of the total surface area and lateral surface area of a cube.

#### Solution

Cube total surface area 6a^2

Where, a = edge of cube

And, lateral surface area= LSA =4a^2

Where a =edge of cube

∴Ratio of TSA and LSA =(6a^2)/(4a^2)is 3/2 is 3:2
