The surface area of the pencil is the amount of space it covers

The surface area of the pencil is 61 square centimeters

How to determine the surface area?

The given parameters are:

H = 20 cm

L = 0.5 cm

The surface area (SA) is then calculated as:

SA = 6LH + 3[tex]\sqrt 3[/tex]L^2

This gives

SA = 6 * 0.5 * 20 + 3[tex]\sqrt 3[/tex] * 0.5^2

Evaluate the sum

SA = 61

Hence, the surface area of the pencil is 61 square centimeters
