Answer 1

Answer:

At least 18 solid balls

Step-by-step explanation:

Volume of rectangular tank:

    $\sf \boxed{\bf Volume \ of \ rectangular \ tank = length* width * height}$

Volume of empty space = Volume of the full tank - Volume of the tank till the water.

                                        = 20*10*13 - 20*10*11

                                        = 2600 - 2200

                                        = 400 cm³

Volume of 1 solid ball = 23 cm³

Number of solid ball to make the tank overflow = 400 ÷ 23

                                                                               ≈ 18 solid balls
