Water is poured into container A so that it’s 2/3 full.
tigry1 [53]

Step-by-step explanation:

Volume of Container A

= (8cm)(8cm)(12cm) = 768cm³.

Volume of water = 2/3 * Volume of Container A

= (2/3) * 768cm³ = 512cm³.

Base Area of Container B

= (10cm)(10cm) = 100cm².

Hence Depth of water in Container B

= 512cm³ / 100cm² = 5.12cm.
