Question:
Find the ratio of the total surface area and lateral surface area of a cube.
Solution:
Total Surface Area of the Cube $(T S A)=6 a^{2}$
Where, a = edge of the cube
And, Lateral surface area of the Cube (LSA) $=4 \mathrm{a}^{2}$
Where, a = edge of the cube
Hence, Ratio of TSA and LSA $=6 a^{2} / 4 a^{2}=3 / 2$ is $3: 2$.
