Question

What is the total surface area of a cube whose side is $0.5$ cm?

• A. $1.5c{m}^2$
• B. $0.25c{m}^2$
• C. $0.125c{m}^2$
• D. $2.5c{m}^2$

Answer 1

The correct option is A $1.5c{m}^2$

The surface area of the cube of side '$a$' is given by,
$S=6a^2$
Here, $a=0.5$ cm
$\therefore$ the total surface area of a cube $=6(0.5{)}^2=1.5c{m}^2$
