Answer:
13.5 kg
Step-by-step explanation:
Find the volume of the block of ice:
Volume = Length x Breadth x Height
Volume = 40 x 25 x 15 = 15000 cm³
Find the equivalent of the ice in term of water:
1 cm³ of ice = 9/10 cm³ of water
15000 cm³ of ice = 9/10 x 15000 cm³ of water
15000 cm³ of ice = 13500 cm³ of water
Find the weight of the ice:
1 cm³ = 1 g
13500 cm³ = 13500 g = 13.5 kg
Answer: The block of ice weighs 13.5 kg
