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

The surface area of the pencil is 61 square centimeters

<h3>How to determine the surface area?</h3>

The given parameters are:

H = 20 cm

L = 0.5 cm

The surface area (SA) is then calculated as:

SA = 6LH + 3\sqrt 3L^2

This gives

SA = 6 * 0.5 * 20 + 3\sqrt 3 * 0.5^2

Evaluate the sum

SA = 61

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

mestny [16]
Let the two numbers be x and y.

x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________


2x = 98

x = 98/2
 
x = 49


From    x + y = 86

49 + y = 86

y = 86 - 49

y = 37

The numbers are 49 and 37.
