Question

Find area of cube if l=6 cm

Answer 1

Answer:

Side = 6 cm

Area of cube = a × a × a

= ( 6 × 6 × 6 ) cu. cm

=216 cu. cm

Answer 2

Given

L=6cm

TO find

Area of the cube

For this, we can just simply use the basic mathematical equation of square

The steps to find the area of a square is as follows

We know that the area of the  square is $6a^{2}$----------- equation 1

also known as the t.s.a of the square that is nothing but (total surface area)

so we have "a" or l= 6cm

so $6*6^{2}$ =  6*36= $216cm^{2}$

so we obtain that the area of the cube of side 6cm is $216cm^{2}$

Extra tip or point

we can also write the equation for square as (6*a*a) it is absolutely the same
