Question

On world health day NGO constructed cuboidial water tank in a society whose volume is bracket 27+125xcube +135xsquare+225xbracket cube units

Answer 1

Answer:

(3 + 5x)³

(3x + 5)³

Step-by-step explanation:

Volume of Tank = 27 + 125x³ + 135x + 225x²

= 3³ + (5x)³  + 45x(3 + 5x)

= 3³ + (5x)³  + 3 * 3 * 5x (3 + 5x)

using (a + b)³ = a³ + b³ + 3ab(a + b)

a = 3  , b = 5c

= (3 + 5x)³

or

27x³ + 125 + 135x² + 225x

= (3x)³ + 5³ + 45x(3x + 5)

= (3x)³ + 5³ + 3(3x)5(3x + 5)

= (3x + 5)³
