Question

What is the difference between total surface area and lateral surface area of a cube whose edge length is 1 cm?

• A. $2c{m}^2$
• B. $4c{m}^2$
• C. $3c{m}^2$
• D. $6c{m}^2$

Answer 1

The correct option is A $2c{m}^2$

Given, edge length of the cube (a) = 1 cm
The required difference = total surface area - lateral surface area
$=6a^2-4a^2$
$=2a^2$
$=2\times 1^2$
$=2c{m}^2$
