Question

Find the cubes of the following numbers by column method: $35$

✓

Answer

We have to find the cube of 35 using column method. We have: $a = 3 $and $b = 5$

Column $I$	Column $II$	Column $III$	Column $IV$
$a^3$	$3 \times a^2 \times b$	$3 \times a \times b^2$	$B^3$
$3^3= 27$	$3 \times a^2\times b = 3 \times 3^2\times 5 = 135$	$3 \times a \times b^2= 3 \times 3 \times 5^2= 255$	$5^3= 125$
$+15$	$+23$	$+12$	$125$
$42$	$158$	$237$
$42$	$8$	$7$	$5$
