Question

How many ice cubes of edge 2 cm can fit into an ice tray of measure 2 cm × 4 cm × 9 cm ?​

Answer 1

Answer:

9 ice cubes will fit in the tray

Answer 2

Step-by-step explanation:

• Total Surface Area of cube = 6side^2

So Total surface area of ice cube= 6*2*2cm^2

• Total Surface area of ice tray =2(lb+bh+hl)

So,Total Surface Area of ice tray =2(lb+bh+hl)

So, No. of ice cubes can be put in tray = Total surface area of tray/Total Surface Area of ice cube = 2(2*4+4*9+9*2)/6*2*2=2(8+36+18)/24=2(62)/24=5.33

So,approx 5 ice cubes can be fit into an ice tray✌✌
