Mass of container = 800g = 0.8kg

Mass of container full of water = 15.6kg

Mass of container = 800g = 0.8kg

Mass of container full of water = 15.6kg

Mass of water alone = 15.6-0.8 = 14.8kg

Volume of cylinder = πr²h

Volume of cylinder = πr²h

If the diameter doubles, so does the radius. The question says the height also doubles.

New radius = 2r, New height = 2h

New formula = π(2r)²(2h)= π4r²2h = 8(πr²h)

Hence, the volume increases by 8 times. Therefore, weight increases by 8 times too. Volume of water = 14.8kg x 8 = 118.4 kg

Since the height and diameter double, the dimensions of the sheet also double.

Let us assume the original sheet had dimensions of 2mx2m. The area would be 4m². The new dimensions would be 4mx4m and the area would be 16m. Therefore, area of the sheet increases by 4 times, meaning that the weight of the sheet also increases by 4.

Weight of new sheet = 0.8kg x 4= 3.2kg

Total weight of new container full of water = 118.4 kg + 3.2 kg = 121.6 kg
